HV9982 - LED Drive IC

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.

Features

  • Switch mode controller for single-switch converters.
  • Closed loop control of output current - Buck - Boost - SEPIC.
  • High PWM dimming ratio.
  • Internal 40V linear regulator.
  • Constant frequency operation.
  • Programmable slope compensation.
  • Linear and PWM dimming.
  • +0.2A/-0.4A gate drives for the switching FETs.
  • Output short circuit protection.
  • Output over voltage protection.
  • Hiccup-mode protection.
