  • Description

    The JW®3655A is a buck boost converter targets HVDC fast charging system. The JW3655A supports 1 to3 cells Li-ion battery, the full charge voltage and charge current can be programmed through external resistor. The JW3655A 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. JW3655A guarantees robustness with thermal protection and battery under voltage lockout.
