TJ33120 HV LED Driver

The TJ33120 is high voltage LED driver with the internal MOSFET is intended for LED chain control. The TJ33120 ensures control and stabilization of the current average value in the LED circuit by means of commutation the current pulses in the inductor in the PWM mode with the fixed switch-off time w.
