HV9985 - LED Driver

Description

The HV9985 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.

Features

  • Switch mode controller for single-switch converters.
  • Gate drivers optimized for driving Logic Level FETs.
  • 0.25A sourcing.
  • 0.5A sinking.
  • Typical ±2% absolute and string-to-string current accuracy (with ±1% sense resistors).
  • High PWM dimming ratio up to 5000:1.
  • 10-40V input range.
  • Constant frequency operation up to 1.0MHz.
  • On-chip clock or external clock option.
  • Programmable slope compensation.
  • Linear and PWM dimming.
  • Output shor.
