HV9961 Datasheet LED Driver

Manufacturer: Microchip Technology

Overview: HV9961 LED Driver with Average-Current Mode Constant-Current.

General 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.

This greatly improves accuracy as well as the line and load regulations of the LED current without any need for loop compensation or high-side current sensing.

Key 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.
