Typical Application Circuit for LTC3838EUHF-1 4.5V to 14V Input, 1.2V/50A 2-Phase Single Output, 300kHz, DCR Sense, DTR Enabled, 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
