致新(GMT)原装电视显示屏方案-G1621R51U-K--TQFN4X4-24-科瑞芯电子

General Description
The G1621 is 14+1 channel digital programmed voltage
reference buffer suitable for TFT-LCD application.
It consists of 14 channels buffered voltage generator
for gamma curve adjustment, two register banks which
can store two different sets of gamma reference values
and 1 channel for VCOM buffer. The digital data is
programmed through I2C interface then store in the
integrated NVM. The NVM allows two sets of gamma
data and VCOM data to be stored. The gamma data
sets can be dynamic switched between two register
banks obtains rapid changes on gamma curve. All of
the channels are capable of driving heavy capacitive
loads and offering large current sufficiently.
(Vcom: 100mA ; Gammas: 25mA)
