11.3 Circuit Changes
All components other than those listed below, including the transformer, are identical to
the original EP-16 design. The modified EP-16 schematic is shown in Figure 30.

LNK501P replaced with LNK520P.
20.5 kΩ to 16.2 kΩ.
Reduced feedback resistor value to correct for increased value of R2 (reduces no-
load voltage).
100 Ω to 430 Ω.
Increased leakage filtering to ensure supply enters auto-restart when output
voltage is below 2 V in CC region.
