LTC3828 Datasheet (Linear Technology) - Dual 2-Phase Step-Down Controller

LTC3828, Dual 2-Phase Step-Down Controller

The LTC®3828 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 for a phase-lockable frequency of up to 550kHz.

The TRCKSS pin provides both soft-start and tracking funct
