Preliminary Datasheet
LP6286
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 pu...
