Device Overview

Summary

The HV9982 is a three-channel, closed loop, peak current mode PWM controller for driving a constant output current. It can be used for driving either RGB LEDs or multiple channels of white LEDs. The HV9982 includes a 40V linear regulator which provides an 8.0V supply to power the IC. The switching frequencies of the three converters are controlled by an external clock signal. The channels operate at a switching frequency of 1/12th of the external clock frequency and are positioned 120O out-of-phase to reduce the input current ripple. Each converter is driven by a peak current mode controller with output current feedback. The three output currents can be individually dimmed using either linear or PWM dimming. The IC also includes three disconnect FET drivers which enable high PWM dimming ratios and also help to disconnect the input in case of an output short circuit condition. HV9982 includes a hiccup mode protection for both open LED and short circuit condition with automatic recovery when the fault clears.
