General Description

The HV9861A is a patented, average-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, and therefore greatly improves the accuracy, line and load regulation of the LED current without any need for loop pensation or highside current sensing.

The output LED current accuracy is ±3%.

Key Features

  • Fast average current control Programmable constant off-time switching PWM / linear dimming input Output short circuit protection with skip mode Ambient operating temperature -40OC to +125OC Pin-compatible with the HV9910B and HV9961 HV9861A General.
