  • Description
    The JW®3655E is a buck boost converter targets HVDC fast charging system. The JW3655E supports 1 to 4 cells Li-ion battery, the full charge voltage and charge current can be programmable through external resistor. The JW3655E implements the Buck Boost converter with an H-bridge. The integrated low R DS (on) MOSFET minimizes physical footprint, maximizes  charge  efficiency.  Built-in  loop compensation simplifies the circuit and design. PFM is engaged to maintain high efficiency at light load current.
