Characteristics STEVAL-ISC001V1
1 Characteristics
As such, it falls within the scope of the European "Code of Conduct on Efficiency of External
Power Supplies" and is required to meet efficiency standard under no-load conditions as
specified in the following table:

This evaluation board complies with the "Phase 2" requirements. The minimum switching
frequency (60 kHz @ V
= 100 VDC) has been chosen trading off between the transformer
IN
size and frequency-related losses. To provide room for the leakage inductance spike, an
800 V MOSFET (STP5NK80ZFP) is used.
