The G5562A DC-DC converter provides regulated voltages required by thin-film transistor (TFT) liquid crystal displays (LCD) panels in TQFN package. One step-up converter, one step-down converter, and two charge pumps convert the 8V to 14V input voltage into four output voltages. These features complete the powersupply requirements of large screen LCD panels. The step-up converter provides source voltages VS and the step-down converter provides logic voltage for the system. The dual charge pumps independently generate adjustable regulated output voltages VGL and VGH to bias the LCD. These four blocks operate with a fixed switching frequency of 500kHz or 750kHz. Both step-up and step-down converters operate in asynchronous switch mode. Current mode control provides fast transient response and eases loop stabilization. Fault protection include [ … ]
