LTC3780 Datasheet 4-switch Buck-boost Controller

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3780 is a high performance buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage.

The constant frequency current mode architecture allows a phaselockable frequency of up to 400kHz.

With a wide 4V to 30V (36V maximum) input and output range and seamless transfers between operating modes, the LTC3780 is ideal for automotive, tele and battery-powered systems.
