MAP3204

Confidential Preliminary Datasheet Version 0.0 MAP3204 – 4-Channel LED Driver for High Brightness LEDs MAP3204 4-channel LED Driver for High Brightness LEDs 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. It features PWM dimming control, internal soft-start and 1.5% current matching between channels and has protections like output over-voltage and LED short/open and UVLO. The MAP3204 is available in 16 leads E-TSSOP and 20 leads SOIC package with Halogen-free (fully RoHS compliant). Features 7V to 36V Input Voltage Range Drive up to 4 Channels 150mA Output Current per Channel 1.5% Current Matching Programmable Boost Switching Frequency : 100kHz to 500kHz PWM Dimming : up to 22kHz Current Mode Control Boost Over Current Protection Output Over Voltage Protection LED Short/Open Protection UVLO 16 leads E-TSSOP and 20 leads SOIC Applications High Brightness white LED backlighting for mid and large size LCD module General LED lighting applications Ordering Information Part Number MAP3204SIRH MAP3204TERH Top Marking MAP3204 MAP3204 Ambient Temperature Range -40℃ to +85℃ -40℃ to +85℃ Package ...
