HIGH VOLTAGE GATE DRIVER IC WITH RAMP DRIVER

摘要

PROBLEM TO BE SOLVED: To provide a high voltage gate driver IC with ramp driver capable of reducing a system cost and saving a space of a system by eliminating an external auxiliary ramp generating circuit of a plasma display panel gate driver IC (HVIC).;SOLUTION: The high voltage gate driver IC with ramp driver comprises: a sensor 24 for sensing a voltage between both terminals of a power switch 16; a reference generator 26 for generating a reference voltage signal in accordance with the external setting; and a feedback circuit 30 of providing a feedback gain in order to control a gate of the power switch 16, wherein the feedback circuit 30 causes the voltage between both terminals of the power source switch 16 to follow to the reference and stabilizes the voltage and, thereby, the HVIC 22 minimizes circuit components on the outside of the HVIC 22 and performs a ramp driving function.;COPYRIGHT: (C)2008,JPO&INPIT
