General Description<\/h3>\n\n\n\n

The ELP6285 includes a high-efficiency boost regulator, a VCOM buffer, and dual charge pump controller for active matrix TFT LCDs.
The converter is a high switching frequency current-mode regulator with an integrated N\u0002Channel 200m\u2126 MOSFET that allows the use of small inductors and ceramic capacitors.
The Unity-Gain buffer can drive the VCOM voltage, that features high short-circuit current, fast slew rate and rail-to-rail inputs and outputs The positive\/negative charge pump controller provides regulated Gate-On voltage.<\/p>\n\n\n\n

The regulation of the charge pump is generated by the internal comparator that senses the output voltage and compares it with an internal reference.<\/p>\n\n\n\n

Other features include under-voltage protection, short circuit protection, thermal shutdown protection and under-voltage lockout (UVLO). The ELP6285 is available in a space saving QFN3*3 (0.5mm pitch) package.<\/p>\n\n\n\n
