제품 개요
The LT1307BCS8#PBF 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 LT1307B does not shift into Burst Mode® operation at light loads, eliminating low frequency output ripple at the expense of light load efficiency. The device contains a low-battery detector with a 200mV reference and shut down to less than 5µA. No load quiescent current of the LT1307B is 1mA 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.
