LTC3611EWP

10A, 32V Monolithic Synchronous Step-Down DC-DC Converter

DESCRIPTION

The LTC® 3611 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 10A output current from a 4.5V to 32V 36V maximum input supply. It uses a constant on-time valley current mode 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 compensated for variations in VIN and VOUT.
