LTC3850-2 Datasheet (Linear Technology) - 2-Phase Synchronous Step-Down Switching Controller

LTC3850-2, 2-Phase Synchronous Step-Down Switching Controller

The LTC®3850-2 is a high performance dual synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages.

A constant-frequency current mode architecture allows a phase-lockable frequency of up to 780kHz.

Power loss and supply noise are minimized by operating the t
