LTC3614EUDD#PBF IC REG BUCK ADJUSTABLE 4A 24QFN Analog Devices Inc.

 

Description

The LTC®3610 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 12A output current from a 4V to 24V (28V 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 compensated for variations in VIN and VOUT.
The LTC3610 can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference while discontinuous mode provides high efficiency by reducing switching losses at light loads.
