LTC3609 Overview
The LTC®3609 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 6A output current from a 4V to 32V (36V maximum) input supply. It uses a valley current control architecture to deliver very low duty cycle operation at high frequency with excellent transient response. The operating frequency is selected by an external resistor and is pensated for variations in VIN and VOUT.
