  • Description

    The JW®3653A is a buck boost converter targetsHVDC fast charging and discharging power bank.

    The JW3653A supports 1 to3 cells Li-ion battery, the output voltage can be programmable up to 20.0V through external resistor.

    The JW3653A 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, maximizes charge/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.

    JW3653A guarantees robustness with thermal protection and battery under voltage lockout.
