Introduction

The LTC3610 is a high power monolithic synchronous step-down DC/DC regulator that can deliver up to 12A of continuous output current from a 4V to 24V (28V maximum) input supply. It is a member of a high current monolithic regulator family (see Table 46.1) that features integrated low RDS(ON) N-channel top and bottom MOSFETs. This results in a high efficiency and high power density solution ...
