The CXSB6617A/CXSB6617A-1 is a buck boost convertertargetsHVDC fast charging and discharging power bank. The CXSB6617A/CXSB6617A-1 supports 1 to3 cells Li-ion battery, the output voltage can be programmable up to 20.0V through external resistor.  The CXSB6617A/CXSB6617A-1 implements the Buck Boost converter with an H-bridge, which can maintain output regulation for input voltage whether greater or less than output voltage. The integrated low Rds(on) MOSFET minimizes physical footprint, maximizescharge/discharge efficiency, which reduces the power dissipation during discharge. Constant current control is utilized to protect the device from overshooting in unwanted conditions. Built-in loop compensation simplifies the circuit and design. PFM is engaged to maintain high efficiency at light load current. CXSB6617A/CXSB6617A-1 guarantees robustness with thermal protectionand battery under voltage lockout.
