LTC3728 Datasheet (Linear Technology) - 2-Phase Synchronous Step-Down Switching Regulator

LTC3728, 2-Phase Synchronous Step-Down Switching Regulator

The LTC®3728 is a dual high performance step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages.

A constant-frequency current mode architecture allows phase-lockable frequency of up to 550kHz.

Power loss and noise due to the ESR of the input capacitors are
