General Description
HV9982 is a three-channel, closed loop, peak-current mode PWM controller designed to drive a constant output current.
It can be used for driving either RGB LEDs or multiple channels of white LEDs.
HV9982 includes a 40V linear regulator which provides an 8.0V supply to power the IC.
