LTC3892 2-Phase Synchronous Step-Down DC/DC Controller

The LTC®3892/LTC3892-1/LTC3892-2 is a high performance dual step-down DC/DC switching regulator controller that drives all N-channel synchronous power MOSFET stages. Power loss and noise are minimized by operating the two controller output stages out-of-phase. The gate drive voltage can be programme.
