HV9961 - LED Driver

Description

The HV9961 is an Average-Current mode constant-current control LED driver IC operating in a constant Off-time mode.

Unlike the HV9910B, this control IC does not produce a peak-to-average error.

Features

  • Fast Average Current Control.
  • Programmable Constant Off-time Switching.
  • Linear Dimming Input.
  • PWM Dimming Input.
  • Output Short-circuit Protection with Skip Mode.
  • 40°C to +125°C Ambient Operating Temperature.
  • Pin-compatible with HV9910B.
