FP6783 Integrated Multi-Channel DC-DC Converters for TFT LCD Panels Description The FP6783 is an integrated power supply solution optimized for medium to large size thin-film transistor (TFT) liquid crystal displays (LCD’s). The boost converter operates at a frequency of 1.2MHz. The integrated N-channel FET has a typical current limit of 4.5A and can support output voltage up to 18V. A positive charge pump with an integrated driver can produce up to 36V of positive gate drive. The GPM is a flicker compensation circuit to reduce the coupling effect of gate lines; the gate-shaping timing is controlled by the timing-controller to modulate the Gate-On voltage, VGHM.
