The G5562 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. .
8V to 14V Input Voltage Range 500kHz/750kHz Fixed Switching Frequency VS Step-Up Converter Current Mode 1% Feedback Accuracy Output Voltage Range up to 20V 3A Switch Current Adjustable Soft Start Adjustable Current Limit VLOGIC Step-Down Converter Current Mode 1% Feedback Accuracy 2.5A Switch Current 2.5ms Internal Soft Start 150mA Negative Charge Pump Driver for VGL 150mA Positive Charge Pump Driver for VGH Integrated High Voltage Switch for Gate Voltage Shaping High Voltage LDO for VREF 0.5% Feedback Accuracy 0.5V Dropout at 60mA Output Current High-.
