A8651 Description
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 pensation, excellent loop stability, and fast transient response. The A8651 uses external pensation to acmodate a wide range of power ponents to optimize transient response without sacrificing stability.
