LTC3850-1 - 2-Phase Synchronous Step-Down Switching Controller

Download the LTC3850-1 datasheet PDF. This datasheet also covers the LTC3850 variant, as both devices belong to the same 2-phase synchronous step-down switching controller family and are provided as variant models within a single manufacturer datasheet.

Description

The LTC®3850 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.
