Patent ID: 7492128

Claim:
A dynamic distribution device for a battery power loop, comprising: a voltage-sensing module, electrically connected to a battery, for sensing a battery voltage of said battery; a power managing logic, electrically connected to said voltage-sensing module, for receiving a sensing result from said voltage sensing module; a power switch circuit, electrically connected to said power managing logic, for operating correspondingly to a control command from said power managing logic; a buck loop, electrically connected to said power switch circuit, for lowering said battery voltage; and a boost loop, electrically connected to said power switch circuit, for raising said battery voltage, wherein said power managing logic commands said power switch circuit for controlling said buck loop to lower said battery voltage to a system output voltage when said power managing logic determines that said battery voltage is higher than said system output voltage, and wherein said power managing logic commands said power switch circuit for controlling said boost loop to raise said battery voltage to a raised output voltage and controlling said buck loop to lower said raised output voltage to said system output voltage when said battery voltage is lower than said system output voltage.
