General Description

The ADP3421 is a hysteretic dc-dc buck converter controller with two auxiliary linear regulator controllers.

The ADP3421 provides a total power conversion control solution for a microprocessor by delivering the core, I/O, and clock voltages.

The optimized low-voltage design is powered from the 3.3 V system supply and draws only 10 µA maximum in shutdown.
