The HV9961LG-G is an average current mode control LED Driver IC operating in a constant OFF-time mode. Unlike HV9910B, this control IC does not produce a peak-to-average error and therefore greatly improves 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 with a current limit comparator for hiccup-mode output short circuit protection. The HV9961 can be powered from an 8 to 450V supply. A PWM dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 275mV reference or controlled externally through a 0 to 1.5V dimming input. HV9961 is pin-to-pin compatible with HV9910B and it can be used as a drop-in replacement for many applications to improve the LED current accuracy and regulation.
● Fast average current control
● Programmable constant OFF-time switching
● Linear dimming input
● PWM dimming input
● Output short circuit protection with skip mode
