HV9861A Constant Current Control LED Drivers

Microchip HV9861A Average-Mode Constant Current Control LED Drivers are patented LED driver ICs operating in a constant off-time mode. These control ICs do not produce a peak-to-average error, and therefore greatly improve the accuracy, line, and load regulation of the LED current without any need for loop compensation or highside current sensing. The output LED current accuracy is ±3%. Microchip HV9861A Average-Mode Constant Current Control LED Drivers are each equipped with a current limit comparator for hiccup-mode output short circuit protection. Internal over-temperature protection is provided. The internally regulated voltage (VDD) for the HV9861A is 7.5V.
