2 MHz, 4 Channel × 150 mA WLED/RGB Driver with Output Disconnect

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 fo \n• Four LED sinks rated for 150 mA each (600 mA total)\n• Boost converter with integrated 40 V DMOS switch and OVP–load-dump protection\n• 600 kHz to 2.2 MHz switching frequency—ability to operate above the AM band\n• Internal bias supply for single-supply operation (VIN = 6.8 to 21 V)\n• 3.5 µA sh;
