General Description
The EC3655 is a buck boost converter targets HVDC fast charging system. The EC3655 supports 1 to 3 cells
Li-ion battery, the full charge voltage and charge current can be programmed through external resistor.
The EC3655 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. EC3655 guarantees robustness with thermal protection and battery under voltage lockout.
