LTC3780 - 4-Switch Buck-Boost Controller

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.
