AT9932 Overview
The AT9932 is an advanced fixed frequency PWM controller IC designed to control an LED lamp driver using a boost-buck topology that can step the input voltage up or down automatically. The IC provides fast output current transient response and very low susceptibility to input voltage transients, which allows the lamp driver to pass the rigorous electrical transient requirements of SAE J1455 or ISO 7637-2, making the...
