A8650 Overview
The A8650 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 A8650 incorporates current-mode control to provide simple pensation, excellent loop stability, and fast transient response. The A8650 uses external pensation to acmodate a wide range of power ponents to optimize transient response without sacrificing stability.
