Voltage conversion apparatus

摘要

A voltage conversion apparatus includes a DC-to-DC conversion circuit, a sensing circuit, and a compensation circuit. The voltage conversion apparatus is capable of adaptively adjusting the system bandwidth according to the load. The system bandwidth is increased to make the converted voltage responding to the load rapidly when the voltage conversion apparatus is operated at a transient state; and the system bandwidth is decreased to increase the system stability when the voltage conversion circuit is operated at a steady state.
