G2138**1U-TFT_ LCD 2通道电荷泵浦电源集成电路

General Description
The G2138 is a high-performance step-up charge
pump and inverter to generate two output voltages, it
is including pumping controllers for positive and negative
output voltage. The following content contains the
detailed description and the information of component
selection.
The positive charge-pump controller provides adjustable
regulated output AVDD and fixed -1 ratio of AVEE
to supply the TFT.
The pumping clock can be generated by internal circuit,
to reduce the control ** from driver IC. Or the
charge and pump state can be synchronized with LCD
display TE ** (PSYNC), it can reduce the interference
to display quality when states change.
The device requires only five (12 pins) small and
low-cost ceramic capacitors is available in
UDFN1.5X2.4-12 package for smart phone LCD
panel’s driver IC.
