General Description

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 supported by the 0.6V feedback reference voltage.
