LTC3448EDD#TR - Brand New Linear Technology DC Switching Regulators
-
Description
The LTC3448 is a high efficiency, monolithic, synchronous buck regulator using a constant frequency, current mode architecture. It has a supply current of only 32µA during operation, dropping to <1µA in shutdown. With an input voltage range of 2.5V to 5.5V, it is ideally suited for single Li-Ion battery-powered applications. The LTC3448 provides low dropout operation, extending battery life in portable systems.
