JW3655E
The JW3655E 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 RDS(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.
JW3655E guarantees robustness with thermal protection.
