LTC3614 Datasheet (Linear) - 4MHz Monolithic Synchronous Step-Down DC/DC Converter

LTC3614, 4MHz Monolithic Synchronous Step-Down DC/DC Converter

The LTC®3614 is a low quiescent current monolithic synchronous buck regulator using a current mode, constant frequency architecture.

The no-load DC supply current in sleep mode is only 75µA while maintaining the output voltage (Burst Mode operation) at no load, dropping to zero current in shutdown.
