Typical Application for A8513 Wide Input Voltage Range, High Efficiency Fault Tolerant LED Driver
Typical Application for A8513 Wide Input Voltage Range, High Efficiency Fault Tolerant LED Driver. The A8513 is a single-output white LED (WLED) driver for LCD backlighting. It integrates a current-mode boost converter with an internal power switch and one current sink. The A8513 can operate from a single power supply from 4.5 to 40 V, to accommodate start/stop, cold crank, and load dump requirements. A 2 MHz boost converter switching frequency allows the A8513 to operate above the AM radio band
