LT1109ACS8#PBF

LINEAR TECHNOLOGY  LT1109ACS8#PBF  直流/直流开关升压逐步递增稳压器, 可调, 2V-9V输入, 50V/150mA输出, 155kHz, SOIC-8

The is a simple step-up micropower DC-to-DC Converter for use with disk drives. The device requires only four external components to construct a complete DC/DC converter. Current drain is just 360µA at no load, making the device ideal for cost-sensitive applications where standby current must be kept to a minimum. The device features a shutdown pin that turns off the oscillator when taken low. The gated-oscillator design requires no frequency compensation components. High frequency 120kHz operation permits the use of small surface mount inductors and capacitors.
