Control circuit for power transistors in a voltage regulator |
摘要 |
A voltage-regulator circuit with a low voltage drop uses a DMOS power transistor driven by a charge pump. The control circuit includes two feedback loops: a first feedback loop having a high gain and accuracy but low response speed, and a second feedback loop having a wide passband and fast response speed, but low gain.
