Overview
HV9861A LED Driver with Average-Mode Constant Current Control 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-compatible with the HV9910B and HV9961 Applications • DC/DC or AC/DC LED driver applications • LED back-light driver for LCD displays • General purpose constant current source • LED signage and displays • Architectural and decorative LED lighting • LED street lighting Description 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 compensation or high-side current sensing.
The output LED current accuracy is ±3%.
The IC is equipped w...
