초록
In this paper, we propose a high voltage driver IC(HVIC) for LCD and PDP TV power supply. The proposed circuit is included novel a shoot-through protection and a pulse generation circuit for the high voltage driver IC. The proposed circuit has lower variation of dead time and pulse-width about a variation of a process and a supply voltage than a conventional circuit. Especially, the proposed circuit has more excellent pulse-width matching of set and reset signals than the conventional circuit. Also the proposed pulse generation circuit prevent from fault operations using a logic gate. Dead time and pulse-width of the proposed circuit are typical 250 ns, and its variation is maximum 170 ns(68 %) about a variation of a process and a supply voltage. The proposed circuit is designed using
