Figure 14a. Recommended Feedback Circuit.

Please refer to DER-547 as a design example with 440 V output

voltage and 100-300 VAC input voltage. When addressing higher

input voltage designs such as 277 VAC, the output voltage of the PFC

needs to be increased to optimize the performance. If the FEEDBACK

pin resistor divider ratio is changed for higher output voltages, ensure

FEEDBACK and VOLTAGE pin resistor divider ratios are matched. Also

be aware that the brown-in/out will also increase as a result of

VOLTAGE pin resistor divider ratio change. Refer to DER-547 report

for more details.

Voltage de-rating requirements for the power MOSFET, boost diode,

and all design choices should be validated with bench tests.

The recommended circuits are shown in Figures 14a and 14b.
