MAP3249
MAP3249 is 4-channel LED Driver manufactured by MagnaChip.
Description
Features
MAP3249 is a 4-channel LED driver optimized for LED 5V to 28V Input Voltage Range backlight application targeting mid and large size LCD Drive up to 4 Channels module. MAP3249 uses the boost MOSFET externally 60V FB Pin Voltage and 4-channel current sources internally for driving high 0.4V Headroom Voltage brightness White LEDs.
200m A Output Current per Channel
MAP3249 has 60V absolute Max. rating FB pins and Programmable Boost Switching Frequency input voltage is ranged from 8.5V ~ 28V and max LED (100KHz ~ 500KHz) current is 200m A per channel.
LED Current Set by both
MAP3249 has internal soft-start and various PWM and External DC Voltage protections like output over-voltage, LED short/open, Unused Channel Detection open schottky diode, UVLO and thermal shutdown.
Boost Over Current Protection
MAP3249 has an unused channel detection function to Output Over Voltage Protection not boost the output voltage to OVP at start-up.
LED Short / Open Protection
MAP3249 is available 16 leads SOIC and E-TSSOP Schottky Diode Open Protection with Halogen-free (fully Ro HS pliant).
