Typical Application Circuit for LTC3838EUHF-1 1.2V/1.5V, 15A, 350kHz Step-Down Converter. The LTC3838-1 is a dual-channel, PolyPhase synchronous step-down DC/DC switching regulator controller. Two independent channels drive all N-channel power MOSFETs. The controlled on-time, valley current mode control architecture allows for not only fast response to transients without clock delay, but also constant frequency switching at steady load condition
