LTC3728L Datasheet (Linear Technology) - 2-Phase Synchronous Regulators

LTC3728L, 2-Phase Synchronous Regulators

The LTC®3728L/LTC3728LX are dual high performance step-down switching regulator controllers that drive all N‑channel synchronous power MOSFET stages.

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

Power loss and noise due to the ESR of the input capac
