5 W Cellular Phone CCCV (Constant Current Constant Voltage) AC-DC Adapter
This reference document describes a built-and-tested GreenPoint solution for a cellular phone Constant Current Constant Voltage (CCCV) AC-DC adapter. The design is intended for isolated, low power, universal input off-line applications where a constant current/constant voltage output (CCCV) is required for charging NiCd, NiMH, Lithium-ion, or similar batteries. Typical applications would include cell phone chargers and cordless phone chargers. The reference design circuit consists of one, single-sided printed circuit board (PCB) designed to fit into a standard cell phone adapter plastic case.
