HV9861A
Overview
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 compensation or highside current sensing.
- 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
