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 that features integrated low RDS(ON) N-channel top and bottom MOSFETs. This results in a high efficiency and high power density solution with few external components. This regulator family uses a constant on-time valley current mode architecture that is capable of operating at very low duty cycles at high frequency and with very fast transient response. All are available in low profile (0.9mm max) QFN packages.
