                          Device Overview

                          Summary

                          The HV96001 LED driver targets offline lighting applications requiring wide dimming capability. The device is capable of linear dimming and PWM dimming, with the PWM dimming capable of flicker-free dimming down to 0.1% level and lower.

                          The HV96001 is specifically adapted to LED driver designs that accommodate a wide range of the LED load voltage. The device adjusts the output voltage of the AC to DC conversion stage for maintaining a high conversion efficiency over a wide range of the LED load voltage. It also maintains a precise control over the LED current amplitude, thereby maintaining the consistent color temperature.

                          The adaptability of the device to wide range PWM dimming allows for a stable control of the LED current waveform for PWM dimming pulse widths down to
                          250 ns.

                          The HV96001 driver IC adjusts the flyback converter output voltage such that the boost converter (BC) operates with a small difference between the boost converter input and output voltage, also referred to as the headroom voltage. Operating the boost converter with a small headroom voltage, or, more or less equivalent, operating with a small voltage step-up ratio allows the boost converter to be physically small and operate at a higher efficiency.

                          The HV96001 includes two feedback regulators, the flyback regulator for control of the flyback output voltage and the boost regulator for control of the LED current amplitude. An optocoupler driver circuit drives the optocoupler, which in turn provides a control signal for driving the control input of the flyback converter.
