LT3791-1 Datasheet 60v 4-switch Synchronous Buck-boost Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT3791-1 60V 4-Switch Synchronous Buck-Boost Controller.

General Description

The LT®3791-1 is a synchronous 4-switch buck-boost voltage/current regulator controller.

The controller can regulate output voltage, output current, or input current with input voltages above, below, or equal to the output voltage.

The constant-frequency, current mode architecture allows its frequency to be adjusted or synchronized from 200kHz to 700kHz.

Key Features
