LTC3728LX Description
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 capacitors are minimized by operating the two controller output stages out of phase.
