A8651 Datasheet

A8651 Adjustable Frequency Dual Synchronous 2A / 2A Buck Regulator

The A8651 is an adjustable frequency, high output current, PWM regulator that integrates a high-side, P-channel MOSFET and a low-side, N-channel MOSFET. The A8651 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response. The A8651 uses e.
