II. PRODUCT SPECIFICATION
1. Description
The SW5227C includes a boost & 2-channel buck converter, positive & negative charge pump, isolation FET,GAMMA-6Ch, PVCOM, reset function, level shifter 12ch. The device in a QFN 7X7-56L package is optimized for TFT LCD panel. The boost converter provides the regulated supply voltage for source driver ICs of the TFT LCD panel. The 1-channel buck converter provides the regulated supply voltage for logic voltage for the system(Typical=3.3V). The other buck converter is provided for HALF AVDD power of source driver ICs. A positive and negative charge pump driver provide the adjustable regulated output voltage for VGH and VGL. In addition, this device has an built-in input-to-output isolation switch that this makes possible the real isolation. The buck and boost converters operate with a 680KHz, 1.36MHz switching frequency. The level shifter includes 12-channel level shifter with GPM function(6ch) and Non GPM function (6ch). This device has several device protection function such as under voltage lockout (UVLO), soft–start for buck and boost converter, thermal protection, over current and over voltage protection.
