The LTC3610 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. Fault protection is provided by internal foldback current limiting, an output overvoltage comparator and an optional short-circuit shutdown timer. Soft-start capability for supply sequencing is accomplished using an external timing capacitor. The regulator current limit is user programmable. A power good output voltage monitor indicates when the output is in regulation. The LTC3610 is available in a compact 9mm × 9mm QFN package.

Demonstration circuit DC1129A is a synchronous step down converter featuring the LTC®3610, the high efficiency, high density DC/DC regulator. The input voltage range is from 4.5V to 24V. The output voltage is jumper selectable from 1.2V to 2.5V. The rated load current is 12A. The regulator includes the controller and power MOSFETs in the 9mm by 9 mm QFN package. The constant on time valley mode current control structure delivers very low duty cycle with excellent load transient response. The MSFET RDS(on) sensing eliminates external sensing resistor and improves supply efficiency. Discontinuous mode operation and continuous mode at light load is also jumper selectable. A forced continuous control reduces noise and RF interference while discontinuous control provides high efficiency at light loads.
