CONTROL CIRCUIT, BATTERY POWER SUPPLY DEVICE AND CONTROL METHOD |
| 摘要 |
A control circuit can include: (i) a boost mode controller configured to control a switch type converter to operate in a boost mode such that an input current is less than a first input current threshold, where the switch type converter comprises a first terminal coupled to a power supply line from an external power supply to a load, and a second terminal coupled to a battery; (ii) a buck mode controller configured to control the switch type converter to operate in a buck mode; and (iii) a select circuit configured to select either the boost mode controller or the buck mode controller to control the switch type converter based on a detected value of the input current of the external power supply and a detected value of a battery charging/discharging current. |

1. A control circuit, comprising:
a) a boost mode controller configured to control a switch type converter to operate in a boost mode such that an input current is less than a first input current threshold, wherein said switch type converter comprises a first terminal coupled to a power supply line from an external power supply to a load, and a second terminal coupled to a battery; b) a buck mode controller configured to control said switch type converter to operate in a buck mode; and c) a select circuit configured to select either said boost mode controller or said buck mode controller to control said switch type converter based on a detected value of said input current of said external power supply and a detected value of a battery charging/discharging current. |
