Typical Application showing calculated values for A8515 LED Driver. The A8515 is a multi-output white LED (WLED) driver for LCD backlighting in consumer and industrial displays. It integrates a current-mode boost converter with an internal power DMOS switch and two current sinks. The boost converter can drive up to 24 LEDs: 12 LEDs per string at 120 mA. The LED sinks can be paralleled together to achieve higher LED currents, up to 240 mA. The A8515 can operate from a single power supply, from 5 to 40 V
