Introduction
The LTC1772 is a step-up, step-down, and step-up/step-down DC/DC switching regulator controller that operates from a 2.5V to 9.8V supply. It can be configured for boost, buck, or buck-boost topologies, providing a single output voltage. The LTC1772 uses a constant-frequency, current-mode architecture to regulate the output voltage and can operate at switching frequencies up to 550kHz.
