General Description
The MAP3204 is a 4-channel LED driver optimized for LED backlight application targeting mid and large size LCD module. It uses the boost MOSFET externally and 4-channel current sources internally for driving high brightness white LEDs.
Input voltage of the MAP3204 is ranged from 7V ~ 36V and max. LED current is 150mA per channel. It can increase the output voltage depending on the drain voltage rating of boost MOSFET.
