Datasheet 3A 380KHz 18V Buck DC to DC Converter XL1530 Features General Description n Wide 3.6V to 18V Input Voltage Range The XL1530 is a 380KHz fixed frequency n Output Adjustable from 0.8V to 16V PWM buck (step-down) DC/DC converter, n Maximum Duty Cycle 100% capable of driving a 3A load with high n Minimum Drop Out 0.6V efficiency, low ripple and excellent line and n Fixed 380KHz Switching Frequency load regulation. Requiring a minimum n 3A Constant Output Current Capability number of external components, the regulator n Internal Optimize Power MOSFET is simple to use and include internal n High efficiency frequency compensation and a n Excellent line and load regulation fixed-frequency oscillator. n TTL shutdown capability n EN pin with hysteresis function The PWM control circuit is able to adjust the n Built in thermal shutdown function duty ratio linearly from 0 to 100%. An enable n Built in current limit function function, an over current protection function n Built in output short protection function is built inside. When short protection function n Available in SOP8 package happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built in to minimize Applications external component count. n LCD Monitor and LCD TV n Digital Photo Frame n Set-up Box n ADSL Modem n Telecom / Networking Equipment Figure1.
