LTC3612 Datasheet 4mhz Monolithic Synchronous Step-down DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3612.

General Description

The LTC®3612 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 70µA while maintaining the output voltage (Burst Mode operation) at no load, dropping to zero current in shutdown.

The 2.25V to 5.5V input supply voltage range makes the LTC3612 ideally suited for single Li-Ion as well as fixed low voltage input applications.
