JW3655-1

JW3655 JW3655-1 Parameters Subject to Change Without Notice High Efficiency, 3A, Multi-Cells Li-Ion Battery Charger DESCRIPTION The JW®3655 is a buck boost converter targets HVDC fast charging system. The JW3655 support 1 to 3 cells Li-ion battery, the full charge voltage and charge current can be programmable through external resistor. The JW3655 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. JW3655 guarantees robustness with thermal protection and battery under voltage lockout. Company’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of JoulWatt technology Inc. FEATURES Integrate low RDS (on) power MOSFET Wide input range: 3.0V-16.0V, Support 1 to 3 cells battery charge. Full charge voltage: 1.2V-16.0V through external resistor...
