FP6783
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. It also can delay the Gate-On voltage during power-on to achieve a correct power-on delay time and the falling time of the Gate-On voltage are programmable by external capacitor and resistor.
The FP6783 is available in a thin 20-pin 5x5 mm TQFN green package.
