DC/DC converter using bipolar transistor, method of manufacturing the same and DC power supply module using the same |
摘要 |
A DC/DC converter is comprised of a bipolar transistor, an inductor, a smoothing capacitor, an input terminal, an output terminal, and a grounded terminal. A base of the transistor includes a silicon germanium layer. The bipolar transistor has a high switching speed and a low on-state voltage through an optimization of a structure of the transistor.
