Summary
2 MHz, 4 Channel 횞 150 mA WLED/RGB Driver
Description
The A8511 is a multioutput WLED/RGB driver for backlighting medium-size displays. It is a fully integrated high-brightness (HB) LED driver solution that does not require external power devices to complete the backlighting design criteria. The A8511 integrates FETs for a boost converter as well as four 150 mA current sinks, offering a complete integrated solution at HB LED current levels. LED channels can be tied together for up to 600 mA sink capability. It can work from a single power supply of 6.8 to 21 V and withstand up to 40 V. The boost converter is a constant frequency, current-mode converter.
