  • Patent number: 10027155
    Abstract: The present disclosure relates to a power management circuit and a mobile terminal having a first switch for blocking current. The first switch blocks an input of an external power supply in a case that a predetermined load operates in a large current/voltage mode. A bi-directional DC converter boosts a battery voltage and supplies it to the load. Thus, the circuit is simplified and the number of components is reduced for power management.
