TC7735FTG

System power management IC for TFT / low-temperature polysilicon liquid crystal display

1. Summary

The TC7735FTG is a system power management IC for liquid

crystal module of TFT and low-temperature polysilicon. It can

generate each voltage level, which the liquid crystal display

(LCD) driver requires. In addition, the TC7735FTG can generate

the high-voltage power supply for source driver and gate driver

and incorporates VCOM amplifier circuit. So, it can drive the LCD

of TFT and low-temperature polysilicon easily by itself.

The TC7735FTG can also output the required voltage to

connect various LCD drivers by incorporating the function of

adjusting voltage. This optimizes the characteristics of whole LCD

Weight: 0.06 g (Typ.)

system. And the protection functions like the over current

protection circuit and the under voltage lockout circuit are

incorporated to improve safety in driving the IC.
