HV9982 - Switch Mode LED Driver IC

Description

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.

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 www. DataSheet4U. com.
