LTC3868-1 Dual 2-Phase Synchronous Step-Down Controller

The LTC®3868-1 is a high performance dual step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. Power loss and noise due to the input capacitor ESR are mini.
