The CXSB6618A/CXSB6618A-1 is a buck boost convertertargetsHVDC fast charging system. The CXSB6618A/CXSB6618A-1 supports 1 to3 cells Li-ion battery, the full charge voltage and charge current can be programmed through external resistor. The CXSB6618A/CXSB6618A-1 implements the Buck Boost converter with an H-bridge. The integrated low RDS(on) MOSFET minimizes physical footprint, maximizescharge efficiency. Built-in loop compensation simplifies the circuit and design. PFM is engaged to maintain high efficiency at light load current. CXSB6618A/CXSB6618A-1 guarantees robustness with thermal protectionand battery under voltage lockout.
