Evaluation Board for 80W PFC Supply
In the range up to 80W, there is no need to use a bypass diode; the current depends on C
out
in addition
with possible start current on the load. In case of C
out=
47µF there is a max. current about 9A in a time
window of 4ms. The rectifier, inductors and boost- diode (R
sense
– PE4301) can handle it for such a
short time.

5 Description
The EVA4301-80 was designed to help understand and evaluate the features of the PE4201/PE4301
Power Factor Correction IC. Used external devices are standard components chosen for safe operation
and do not represent a completely fine-tuned OEM application. The BOM (bill of material) for a final
application may look slightly different.
The PE4201 is a wide input range controller IC for active power factor correction converters in CRMode
with voltage mode PWM control.
The PE4301 is a wide input range controller IC for active power factor correction converters in CCMode
with voltage mode frequency and PWM control.
Please take caution since the board operates at 405V DC.
