Abstract

This work aims to present an High Voltage High Power and High Frequency CMOS DC-DC converter able to work in both Flyback and Boost configurations, designed for automotive applications. The system, implemented in Austriamicrosystems 0.35um HVCMOS technology, is able to manage input voltages from 2.5V up to 36V and generates a programmable output voltage from 6 to 36V with an output current up to 900mA. To improve EMC/EMI system performances, dithering of switching frequency and slope controlling of the gate driver have been implemented.
