Preliminary Datasheet - MAP3702
600kHz 1-CH White LED Driver for Mobile Backlight
General Description
MAP3702 is an 1-channel LED driver optimized for LED backlight application targeting mobile LCD module. MAP3702 uses 40V absolute Max. rating boost
MOSFET internally and input
voltage is ranged from 2.7V ~ 5.5V. The boost converter runs at 600kHz fixed switching frequency. The default LED current is set by external resistor and the feedback
voltage is regulated up to 200mV. Two dimming controls are available; 32 dimming steps using the SWIRE interface and filtered-PWM control. MAP3702 has various protections like over-current, output over-
voltage protection for open-LED faults, thermal shutdown and UVLO. MAP3702 is available 2mm X 2mm 6 leads DFN package with Halogen-free (fully RoHS compliant).
