ADP1874 Datasheet (Analog Devices) - Synchronous Buck Controller

ADP1874, Synchronous Buck Controller

The ADP1874/ADP1875 are versatile current mode, synchronous step-down controllers.

They provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo fixed frequency with a programmable current limit, current control scheme.

In addition, the
