HV9961 LED Driver with Average-Mode Constant Current Control
Features
► ► ► ► ► ► ► Fast average current control Programmable constant off-time switching Linear dimming input PWM dimming input Output short circuit protection with skip mode Ambient operating temperature -40OC to +125OC Pin-compatible with the HV9910B
General Description
The HV9961 is an average current mode control LED driver IC operating in a constant off-time mode. Unlike HV9910B, this control IC does not produce a peak-to-average error, and therefore greatly improves accuracy, line and load regulation of the LED current without any need for loop compensation or high-side current sensing. The output LED current accuracy is ±3%.
