The HV9989 is a three-channel peak current mode PWM controller for driving single switch converters in a constant output current mode. It can be used for driving either RGB LEDs or multiple channels of white LEDs. The HV9989 featuresproprietary PWM dimming control algorithm achieving a dimming pulse • Three out-of-phase constant-current boost converters\n• Current loop closed with sub-microsecond PWM dimming pulses supports PWM dimming >20kHz\n• Internal 40V linear regulator\n• External clock input\n• External individual reference inputs\n• Individual PWM dimming inputs \n• Programmable slope c;
