LT3932 Datasheet (Linear Technology) - 2A Synchronous Step-Down LED Driver

LT3932, 2A Synchronous Step-Down LED Driver

The LT®3932 is a monolithic, synchronous, step-down DC/DC converter that utilizes fixed-frequency, peak current control and provides PWM dimming for a string of LEDs.

The LED current is programmed by an analog voltage or the duty cycle of pulses at the CTRL pin.
