AP 5 199
LED Driver
Description
The AP5199 is an average current mode control LED driver IC operating in a constant off-time mode. Unlike
AP5160,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 AP5199 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.
