General Description<\/h3>\n\n\n\n

The EC3653 is a buck boost converter targets HVDC fast charging and discharging power bank.<\/p>\n\n\n\n

The EC3653 supports 1 to 3 cells Li-ion battery, the output voltage can be programmable up to 16.0V through external resistor. The EC3653 implements the Buck Boost converter with an H-bridge, which can maintain output regulation for Input voltage whether greater or less than output voltage.<\/p>\n\n\n\n

The integrated low Rds(on) MOSFET minimizes physical footprint, maximizes charge\/discharge efficiency, which reduces the power dissipation during discharge.<\/p>\n\n\n\n

Constant current control is utilized to protect the device from overshooting in unwanted conditions.<\/p>\n\n\n\n

Built-in loop compensation simplifies the circuit and design. PFM is engaged to maintain high efficiency at light load current.<\/p>\n\n\n\n

EC3653 guarantees robustness with thermal protection and battery under voltage lockout.<\/p>\n\n\n\n
