General Description

The TPS56428 is a D-CAP2 mode synchronous buck converter which is optimized for various power bus regulation needs with a cost effective, low component count, low standby current solution.

The D-CAP2 mode control provides a fast transient response with no external compensation components.

This adaptive on-time control supports seamless transition between PWM mode at higher load conditions and advanced Eco-mode operation at light loads.
