EC3653-16V 3A 4-Switch Buck-Boost Charging/Discharging Converter

EC3653-16V 3A 4-Switch Buck-Boost Charging/Discharging Converter
General description
The EC3653 is a buck boost converter targets HVDC fast charging and discharging power bank.

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.

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.

EC3653 guarantees robustness with thermal protection and battery under voltage lockout.
