LT3667 Datasheet 40v 400ma Step-down Switching Regulator

Manufacturer: Linear Technology Corporation

General Description

The LT®3667 is a monolithic triple power supply posed of a 400mA buck switching regulator and two 200mA low dropout linear regulators (LDOs).

The buck regulator includes a high efficiency switch, a boost diode, and the necessary oscillator, control and logic circuitry.

Current mode topology is used for fast transient response and good loop stability.

Key Features
