Multi-Channel DC-DC Converter for LCD Panel
General Description
The LP6286 includes a high-efficiency boost regulator, a gate pulse modulator (GPM), a voltage detector, 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-Channel 0.2Ω MOSFET that allows the use of small inductors and ceramic capacitors. The OPA can drive the LCD VCOM voltage by Unity-Gain buffer, that features high short-circuit current, fast slew rate and rail-to-rail inputs and outputs. The charge pump controller provides regulated TFT Gate-On voltage. The regulation of the charge pump is generated by the internal comparator that senses the output voltage and compares it with an internal reference. Other features include under-voltage protection, short circuit protection, thermal shutdown protection and under-voltage lockout (UVLO). The LP6286 is available in a space saving QFN-24 (0.5mm pitch) package.
