LTC1877 Datasheet (Linear Technology) - High Efficiency Monolithic Synchronous Step-Down Regulator

LTC1877, High Efficiency Monolithic Synchronous Step-Down Regulator

The LTC®1877 s a high efﬁciency monolithic synchronous buck regulator using a constant-frequency, current mode architecture.

Supply current during operation is only 10μA and drops to < 1μA in shutdown.

The 2.65V to 10V input voltage range makes the LTC1877 ideally suited for both single and dual Li-
