LT1308CS8#PBF

LINEAR TECHNOLOGY  LT1308CS8#PBF  直流/直流开关升压逐步递增稳压器, 可调, 1V-10V输入, 1A输出, 600kHz, SOIC-8

The is a micropower fixed frequency boost DC-to-DC Converter operates from an input voltage as low as 1V. Capable of delivering 5V at load current of 1A from a single Li-ion cell, the LT1308 also features power saving Burst Mode® operation at light loads. High efficiency is maintained over a broad 1mA to 1A load range. The device contains a low-battery detector with a 200mV reference and shuts down to less than 5µA quiescent current. No-load quiescent current is 100µA and the internal NPN power switch handles a 2A current with a voltage drop of just 300mV. High frequency 600kHz switching allows the use of small, surface mount components. The LT1308"s current mode architecture provides fast response to load and line variations.
