Zusammenfassung:The utility model discloses a current control type switch power source which comprises a power supply unit, a current type control chip, a voltage feedback unit and a current feedback unit. The power supply unit is connected with the current type control chip. The voltage feedback unit, the current feedback unit and the current type control chip all together form a voltage closed loop control circuit and a current closed loop control circuit, wherein an inner closed loop is the current control circuit and an outer closed loop is the voltage control circuit. The current control type switch power source is equipped with the voltage closed loop control circuit and the current closed loop control circuit, can reach above 90% in terms of power supply efficiency, helps to overcome defects of out of control of currents, is stable and reliable in performance, fast in response speed and simple in circuit design, and exhibits a good application prospect.
