A8591 Description
TheA8591 is designed to provide the power supply requirements of next generation car audio and infotainment systems. The A8591 provides all the control and protection circuitry to produce a high-current regulator with ±1% output voltage accuracy. The A8591 employs current-mode control to provide simple pensation, excellent stability, and fast transient response.
