RT8576 - Richtek

RT8576 High Voltage 8-CH LED Driver

The RT8576 is an 8-CH LED driver capable of delivering 120mA for each channel. The RT8576 is a current mode boost converter with an adjustable switching frequency via the OSC pin from 100kHz to 1MHz and a wide VIN range from 9V to 28V. The PWM output voltage loop selects and regulates the LED pin with the highest voltage string to 0.6V, hence allowing voltag.
