LT1307CN8#PBF

LINEAR TECHNOLOGY  LT1307CN8#PBF  直流/直流开关升压逐步递增稳压器, 可调, 1V-5V输入, 28V/100mA输出, 600kHz, DIP-8

The is a micropower fixed frequency DC-to-DC Converter operates from an input voltage as low as 1V. First in the industry to achieve true current-mode PWM performance from a single cell supply, it features automatic shifting to power saving Burst Mode® operation at light loads. High efficiency is maintained over a broad 100µA to 100mA load range. The device contains a low-battery detector with a 200mV reference and shut down to less than 5µA. No load quiescent current of the LT1307 is 50µA and the internal NPN power switch handles a 500mA current with a voltage drop of just 295mV. The high frequency 600kHz switching allows the use of tiny surface mount multilayer ceramic MLC capacitors along with small surface mount inductors. The device work with just 10µF of output capacitance and require only 1µF of input bypassing.
