Buck & Boost Charger
Buck & Boost Charger

In addition to Buck-Boost charger, we also provide buck charger based on back topology and boost charger based on boost topology, providing rich charging management solutions for single or multi-cell batteries. Southchip charger automatically controls the trickle current charging, constant current fast charging and constant voltage charging according to battery voltage, provides high-precision charging voltage and current, supports external resistor or I2C interface to set charging voltage and current flexibly, and is equipped with multiple protection functions such as input and output over-voltage protection, under-voltage protection, over-current protection and over-temperature protection to ensure battery charging safety.
