LTC3620 Datasheet (Linear Technology) - Ultralow Power 15mA Synchronous Step-Down Switching Regulator

LTC3620, Ultralow Power 15mA Synchronous Step-Down Switching Regulator

The LTC®3620 is a high efﬁciency, synchronous buck regulator, suitable for very low power, very small footprint applications powered by a single Li-Ion battery.

The internal synchronous switches increase efﬁciency and eliminate the need for external Schottky diodes.

Low output voltages are easily su
