AT9932 Datasheet (Supertex) - Automotive Boost-Buck LED Lamp Driver

AT9932, Automotive Boost-Buck LED Lamp Driver

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, whi
