Typical Application Circuit for LTC3838EUHF-1 4.5V to 26V Input, 1.2V/15A and 1.5V/15A Dual Output, 350kHz, RSENSE, 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
