Product Introduction
The HV9961 is an Average-Current mode constant-current control LED driver IC operating in a constant Off-time mode. Unlike the HV9910B, this control IC does not produce a peak-to-average error. This greatly improves accuracy as well as the line and load regulations of the LED current without any need for loop compensation or high-side current sensing. Its 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 8V–450V supply. It has a PWM dimming input that accepts an external control TTL-compatible signal. In addition, the output current can be programmed by an internal 275 mV reference or controlled externally through a 0V–1.5V linear dimming input.
The HV9961 is pin-to-pin compatible with HV9910B, and it can be used as a drop-in replacement for many applications to improve LED current accuracy and regulation.
