THV6530

Summary

The THV6530 is a controller IC power supply system with boost converter and 2 channel charge pump circuit. The positive and negative charge pumps provide regulated TFT LCD gate -on and gate-off supplies. The chip includes a VCOM buffer.
Soft start / Over current protection / Under voltage protection / Thermal shut down are built in.
Mounted area is reducible by 16-pin QFN.
