A8600 Overview
Designed to provide the power supply requirements of next generation car audio and infotainment systems, the A8600 provides all the control and protection circuitry to produce four high current regulators, each with ±1.5% accuracy. The A8600 includes control circuitry to implement three adjustable, asynchronous buck regulators with integrated MOSFETs. Also, the A8600 provides the control circuitry, gate drivers, and...
