A8582 Description
The A8582 is an adjustable frequency, high output current, PWM regulator that integrates a low resistance, high-side, N-channel MOSFET. The A8582 incorporates current-mode control to provide simple pensation, excellent loop stability, and fast transient response. The A8582 utilizes external pensation to acmodate a wide range of power ponents to optimize transient response without sacrificing stability.
