說明
-
Typical circuit for driving 2 LED strings at up to 35 V at 200 mA per LED string, with thermal derating. The A8501 is a multi-output WLED/RGB driver for medium-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and four current sinks. Each individual current sink is capable of 100 mA, and channels can be combined for up to 400 mA total. It can work from a single power supply of 8 to 21 V, with the ability to ride through transient input voltages as low as 6.8 V and as high as 40 V, and has extensive fault mode protection schemes. It is targeted for use in OEM or aftermarket in-cabin telematics, as well as consumer and industrial LCD display backlighting
