产品详细介绍
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.
