1. General Board Description
The FEB107-001 Evaluation Board is a power factor corrected 12V 20A off-line power supply. It is designed to
meet IEC1000-3-2 over the universal input voltage range of 85 to 265VAC. The Evaluation Board demon-
strates that the FAN4803 can be designed with a low cost single sided PCB at a power level, size, and cost that is
compatible with most desk top computer power supply requirements. The FAN4803 is the replacement for the
ML4803, but either IC will work with this board.
