MAX20070/MAX20070B EVALUATION KIT AVAILABLE Integrated TFT Power Supplies and LED Backlight Drivers General Description The MAX20070/MAX20070B are highly integrated power supplies and LED backlight drivers for automotive TFT-LCD applications. The devices integrate one buckboost converter, one boost converter, two gate-driver supplies, and a boost/SEPIC converter that can power one to two strings of LEDs in the display backlight. The source-driver power supplies consist of a boost converter and an inverting buck-boost converter that can generate voltages up to +15V and -15V. Both sourcedriver power supplies can deliver up to 100mA. The positive source-driver supply regulation voltage (VPOS) is set by connecting an external resistor-divider on FBP.
