DC/DC Converter  
DESCRIPTION  
FEATURES  
TheLTC®3610isahighefficiency,monolithicsynchronous  
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 de-  
liver 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

The LTC3610 can be configured for discontinuous or  
forced continuous operation at light load. Forced continu-  
ous operation reduces noise and RF interference while  
discontinuous mode provides high efficiency by reducing  
switching losses at light loads.
