Charging circuit and the method thereof
A charging circuit adopts a plurality of feedback control circuits, a constant time signal generator and a logic circuit to control the operation of a power switch. The charge circuit needs no oscillator with high frequency, error amplifier with high speed and high accuracy, or compensation circuit with complicated structure, so the system portability is highly improved.
