FP7721BX2
1 The FP7721BX2 is an integrated power supply solution optimized for small to medium size thin-film transistor (TFT) liquid crystal displays (LCD’s). Primarily intended for smart phone and tablet LCD panel’s driver IC. The positive charge pump has an internal switch and typically can support output current up to 100mA at VCI=3.3V. Negative charge pump has an internal switch to generate -1 ratio of VSN and typically can support output current up to 100mA at VCI=3.3V. The pump clock can be synchronized with external signal from driver IC or can be generated by internal circuit fixed to 600kHz. The FP7721BX2 is available in a thin 12-pin 2.4x1.5 mm UTDFN green package.
