THV6520

Summary

The THV6520 is a controller IC power supply system with boost converter and charge pump circuit .The charge pump provide regulated TFT LCD gate-on and gate-off supplies. The chip includes a VCOM buffer and a gate slop circuit and LDO.
Soft start / Over current protection / Under voltage protection / Thermal shut down are built in. Mounted area is reducible by 24-pin QFN.
