LT3922 Low EMI 2MHZ, 333mA Boost LED Driver with SSFM

Low EMI ZMHZ, 333mA Boost LED Driver with SSFM

The LT3922 is a monolithic, synchronous, step-up 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. The LT3922 will maintain ±2% current regulation through an external sense resistor over a wide range of output voltages.
