2003 THRU 2024 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 Ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the Series ULN20xxA/L high-voltage, high-current Darlington arrays feature continuous load current ratings to 500 mA for each of the seven drivers. At an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously, typical power loads totaling over 230 W (350 mA x 7, 95 V) can be controlled. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes. The ULN2003A/L and ULN2023A/L have series input resistors selected for operation directly with 5 V TTL or CMOS. These devices will handle numerous interface needs -- particularly those beyond the capabilities of standard logic buffers. The ULN2004A/L and ULN2024A/L have series input resistors for operation directly from 6 to 15 V CMOS or PMOS logic outputs. Data Sheet 29304F Dwg. No. A-9594 Note that the ULN20xxA series (dual in-line package) and ULN20xxL series (small-outline IC package) are electrically identical and share a common terminal number assignment. The ULN2003A/L and ULN2004A/L are the standard Darlington arrays. The outputs are capable of sinking 500 mA and will withstand at least 50 V in the OFF state. Outputs may be paralleled for higher load current capability. The ULN2023A/L and ULN2024A/L will withstand 95 V in the OFF state. These Darlington arrays are furnished in 16-pin dual in-line plastic packages (suffix "A") and 16-lead surface-mountable SOICs (suffix "L"). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. All devices are rated for operation over the temperature range of -20°C to +85°C. Most (see matrix, next page) are also available for operation to -40°C; to order, change the prefix from "ULN" to "ULQ".

А главное ­ изменились представления о целесообразности использования тех или иных схем для получения заданных параметров. Исчезла категоричность, предписывающая использовать строго определенные структуры для конкретных типов источников электропитания. Возросло влияние экономических, рыночных факторов на выбор схемы преобразователя. Все это сделало возможным то, что еще вчера казалось парадоксальным и даже неправильным. Вот несколько примеров: 1. Однотактные преобразователи стали занимать нишу, традиционно отводившуюся для двухтактных преобразователей мощностью в единицы Вт ­ единицы кВт. 2. Благодаря использованию высокочастотных к

Fax886-3-5645626 Tel886-3-5645656 PS222S PS222S 3-Channel Secondary Monitoring IC With Over-Current Protection And an Additional 12V OCP Channel General Description PS222S is specially designed for switching power supply system. Four important functions of PS222S are the following: over-voltage protection, over-current protection, under-voltage protection and power good signal generating. OVP/UVP (Over-Voltage/Under-Voltage Protection) monitors 3.3V, 5V and 12V to protect our power supply. FPO/ goes to high when one of these supply voltages exceeds their normal operation voltage range. OCP (Over Current Protection) monitors IS33, IS5, IS12 input current sense. Composed of "Iref" and "protection current range resistor", an adjustable over-current condition helps users design OCP easily. An additional OCP channel helps users monitor another 12V rail output current. Power good signal generating can notify personal computer when power supply is ready or power supply is going to shutdown, therefore it can provide a reliable power supply environment.

Итак, сегодня поговорим о том, как нахаляву получить отличное зарядное устройство (ЗУ) для автомобильных 12В аккумуляторов. Понадобятся: левокитайский АТХ БП ($5 за живой и $1 - за дохлый), паяльник, резистор 0.47-0.82 Ом/5-10Вт, метровый кусок крепкого "акустического" провода, пара клешней- терминалов и мультиметр. Схема переделки- на рисунке. Что нужно сделать с БП: 1) выдираем ВСЕ провода, выходящие за пределы корпуса БП. Для удобства можно оставить ~10см куски черного (2 шт.), желтого (1 шт.) и зеленого (1 шт.) проводов. Зачем?- см. схему ;) 2) удаляем по вторичной стороне выпрямители и электролиты по +5, -5 и -12В. Так же выдираем за ненадобностью все, что относилось к +3.3В цепи. 3) выпаиваем и перематываем многообмоточный дроссель: на этом же колечке без зазрения совести можно намотать 40 витков лакированым проводом ~1 кв.мм., что не позволит ему влететь в насыщение даже при 7А зарядном токе. Полученный дроссель ставим обратно вместо бывшей +12В секции многообмоточного дросселя. В принципе, п. 3 делать необязательно, но если не лениво- лучше сделать ;) 4) Подключаем снаружи кнопку к черному и зеленому проводу. Тоже необязательно- можно их просто соединить между собой и вкл/выкл делать клавишей на удлинителе. 5) В разрыв второго черного провода ставим мощный резистор (см. выше) и с него снимаем ООС по току (см. схему). Внимание, резистор может сильно нагреваться в работе, так что размещаем его поближе к пропеллеру внутри БП. 6) Ищем на печатной плате БП резистор между 1-й ногой TL494/KA7500 и бывшим +12В выходом (обычно- порядка 100-300кОм, не помню уже). При неподсоединенном аккумуляторе подбираем этот резистор таким, что- бы на выходе было около +16В, в дальнейшем откалибруем поточнее. 7) К черному (-) и желтому (+) проводам припаиваем кусок акустического провода с клешнями, не перепутайте полярность! 8) Подсоединяем более- менее заряженный аккумулятор с нормальной плотностью электролита и подбираем описанный в п.6 резистор так, что бы на клемах было +14.2В. После нескольких часов зарядки (100% заряд аккуму) напряжение на клемах не должно превышать +15В! Ну, вот и все. Номинал резистора- датчика тока считаем из закона Ома, контрольное напряжение указано на схеме. Для 40-60Ач аккумуляторов рекомендую I=4-5А, для тракторных 90-100Ач можно зарядный ток поднять до 6-7А. Выше 7А не рекомендую, т.к. в типичном левокитайском БП выпрямитель собран на сдвоенных 3А диодах.. Если опасаетесь, что пропеллер сдохнет при подаче на него 16В вместо 12, можно в разрыв любого из его проводов включить резистор 22-47 Ом/0,5-1 Вт (заодно шуметь меньше будет). Ах, да, по бывшему +12В выходу (а ныне- цепи заряда) надо бы заменить электролит, вместо бывшего 1000-2200uF/16В поставить 1000-4700uF/25-63В (если перематывали дроссель, то можно съекономить и поставить 470uF/50В). Вышеописаная конструкция собирается за вечер, еще несколько часов потребуются на тестирование и окончательную подстройку. Если для вас это сложно- купите готовую зарядку, импул

www.ti.com TL494 PULSE-WIDTH-MODULATION CONTROL CIRCUITS SLVS074E ­ JANUARY 1983 ­ REVISED FEBRUARY 2005 FEATURES · · · · · · · Complete PWM Power-Control Circuitry Uncommitted Outputs for 200-mA Sink or Source Current Output Control Selects Single-Ended or Push-Pull Operation Internal Circuitry Prohibits Double Pulse at Either Output Variable Dead Time Provides Control Over Total Range Internal Regulator Provides a Stable 5-V Reference Supply With 5% Tolerance Circuit Architecture Allows Easy Synchronization D, DB, N, NS, OR PW PACKAGE (TOP VIEW) 1IN+ 1IN- FEEDBACK DTC CT RT GND C1 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 2IN+ 2IN- REF OUTPUT CTRL VCC C2 E2 E1 DESCRIPTION The TL494 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application. The TL494 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits. The error amplifiers exhibit a common-mode voltage range from ­0.3 V to VCC ­ 2 V. The dead-time control comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating RT to the reference output and providing a sawtooth input to CT, or it can drive the common circuits in synchronous multiple-rail power supplies. The uncommitted output transistors provide either common-emitter or emitter-follower output capability. The TL494 provides for push-pull or single-ended output operation, which can be selected through the output-control function. The architecture of this device prohibits the possibility of either output being pulsed twice during push-pull operation. The TL494C is characterized for operation from 0°C to 70°C. The TL494I is characterized for operation from ­40°C to 85°C.

It provides protection circuits, power good indicator, fault protection output (FPO) and PSON control. Overvoltage protection (OVP) monitors 3.3 V, 5 V, and 12 V (12-V signal detects via VDD pin). Undervoltage protection (UVP) monitors 3.3 V and 5 V. When an OV or UV condition is detected, the power good output (PGO) is set to low and FPO is latched high. PSON from low to high resets the protection latch. UVP function is enabled 75 ms after PSON is set low and debounced. Furthermore, there is a 2.3-ms delay (and an additional 38-ms debounce) at turnoff. There is no delay during turnon. Power good feature monitors PGI, 3.3 V and 5 V and issues a power good signal when the output is ready. The TPS3510/1 is characterized for operation from ­40°C to 85°C. typical application 5 VSB PGI PGO 12 V 1 8 PGO PGI 2 7 VDD GND 3 6 VS5 FPO 4 5 PSON VS33 0.5 V Drop VSB 5V 3.3 V PSON (From Motherboard) Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
