Maximizing efficiency
This evaluation board has been designed to reach a fair compromise between efficiency performance and EM
emissions compliance.
Nevertheless, if the maximum efficiency is needed, the following actions are suggested:
1.
Remove the snubber circuit consisting of R5 and C25 or choose a lower value for the capacitor C25 (for
example 1 nF)
2.
Bypass the whole EMI filter, by bridging the jumpers X1, X14 and X16
3.
Bypass the output ferrite beads L3 and L5
4.
Replace the main inductor L7 with one that boasts a lower parasitic DC resistance, for example

5.
Bypass gate resistor R8
