The English name of lifting pressure isBuck-Boost, as the name suggests, can both boost pressure and reduce pressure. Regardless of whether the input voltage is lower, higher or equal to the battery string voltage, the chip can automatically control the voltage boost or step-down to realize charge management of the battery string. When the system needs to discharge from the battery string, the controller can reverse boost or reduce the battery voltage to output the required voltage. The controller can also output a voltage lower than, higher than, or equal to the battery string voltage. Single inductance four tubesHThe bridge structure can be switched to a synchronous boost or step-down operation according to the control signal, and is not bound by the traditional boost or step-down operation.
