HV9861A Overview
HV9861A is a patented, average-mode, constant-current control, LED driver IC operating in a constant offtime mode. Unlike the HV9910B, this control IC does not produce a peak-to-average error, which therefore greatly improves the accuracy, line and load regulation of the LED current without any need for loop pensation or high-side current sensing. The output LED current accuracy is ±3%.
HV9861A 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 -40°C to +125°C
- Pin-patible with the HV9910B and HV9961
