BOOST
Buck Boost voltage up and down charging IC is a chip that can charge and control single and multiple batteries. Thanks to Buck Boost architecture, no matter the input voltage is higher or lower than or equal to the battery voltage, the boost charging IC can accurately manage and control the battery charging voltage and current.
