Achieves good output current regulation without the need for any loop compensation.
The Supertex HV9803 LED Driver IC is an open loop average-mode current control LED driver IC operating in a constant off-time mode.
Designed to minimize circuit components & drive long strings of low current LEDs in solid-state replacement bulbs.
Greatly improves current accuracy & line & load regulation of LED current; does not produce peak-to-average error.
For driving high brightness LEDs at 100mA, w/ active low enable input which allows logic level control of the LED.
