EL7520, EL7520A 4-Channel DC/DC Controller NORTECROEMCOMMENMDEENISDDLER9DE76PF4LO5ARACNEEMWENDTEPSAIGRNTS DATASHEET FN7318 Rev 0.00 July 12, 2005 EL7520 and EL7520A are 4-channel DC/DC controllers that provide a complete power supply system for TFT-LCD applications. They consist of a 1MHz PWM boost controller, which generates the main voltage for the column driver, and three LDO controllers for VON, VOFF, and VLOGIC supplies. They also include integrated start-up sequence and start-up delay control. EL7520 and EL7520A operate from 3V to 5.5V. The boost controller can drive a wide range of output current depending on the external FET. It can be programmed to operate in either P-mode for fast transient response or PImode for improved load regulation.
