A low power supply and high frequency driver design for DC-DC converter applications

This paper presents an improved driver circuit design for boost DC-DC converter applications. The circuit possesses the characteristics of low power supply and high speed and is, thus, suitable for portable equipment and mobile applications. The simulation results demonstrate that the design has achieved a low power voltage of 1.0 V, which is ideal for single battery applications. The operational frequency of the circuit can be as high as 1 MHz, which meets the increasing demand for high switch speed. Using Samsung bipolar process, this design has been prototyped, and the testing on chips confirms that the prototypes fully meet design specifications and are ready for commercial products applications.
