MAP3204 - MagnaChip

MAP3204 4-channel LED Driver

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 vo.

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-TSS.
