General Description
The HV9961 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 8.0 - 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 - 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.

The HV9961 employs Supertex’ proprietary control scheme, achieving fast and very accurate control of average current in the buck inductor through sensing the switch current only.
