Voltage Regulators AN1149NFHK 6-ch DC-DC Converter I Overview Unit: mm 4 channels of step-up, 1 channel of step-down and 1 9.0±0.2 7.0±0.1 channel of step-up/down voltage, 6 channels in total have 36 25 been integrated onto a single chip. Each channel can be 24 37 remote-controlled and work with two dry cells. A high (0.75) precision output voltage can be obtained thanks to the 7.0±0.1 9.0±0.2 accurate reference of VREF ±1%. 48 13 I Features 1 12 · Low voltage operation (1.5 V min.)
