The Linear Technology LTC3412 is a monolithic synchronous step-down DC/DC converter using a constant-frequency, current-mode architecture. It operates from an input voltage of 2.625V to 5.5V and provides an adjustable output from 0.8V to 5V while delivering up to 2.5A. Its internal synchronous power switch has 85mΩ on-resistance, and the switching frequency is set by an external resistor or synchronized to an external clock.
