HV9861A LED Driver

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.

HV9861A 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 Applica
