It introduced the work principle of inductive boost converter with PWM modulation in the pa-per. And thus it designed a driving circuit of DC-DC to circuit of OLED chip when the input voltage is 3. 3 V,output voltage is 9 V. The integrated circuit can realize integration of the OLED drive circuit and DC-DC converter circuit. In the simulation,using the TSMC 0. 35μm technology,results showed that the input voltage is 3. 3 V,output voltage stability in 9 V,which meet the requirements of PM-OLED drive control chip.
