LTC3601 Datasheet 15v Monolithic Synchronous Step-down Regulator

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3601 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying up to 1.5A of output current.

The operating supply voltage range is from 4V to 15V, making it suitable for a wide range of power supply applications.

The operating frequency is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors.
