LINEAR TECHNOLOGY LTC3525ISC6-3#TRMPBF 同步升压开关稳压器, 固定, 850mV-4.5V输入, 3V和0.4A输出, SC-70-6
The is a high efficiency synchronous step-up DC/DC Converter with output disconnect that can start up with an input as low as 0.85V. It offers a compact, high efficiency alternative to charge pumps in single cell or dual cell alkaline or Li-Ion applications. Only three small external components are required. The device includes a 0.5R N-channel MOSFET switch and a 0.8R P-channel synchronous rectifier. Peak switch current ranges from 150 to 400mA, depending on load, providing enhanced efficiency. Quiescent current is an ultralow 7µA. Other features include <1µA shutdown current, antiringing control and thermal shutdown.
