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:

Table 1.	No-load conditions
			No-load power consumption
Rated input power
		Phase 1		Phase 2(1)		Phase 3
		01.01.2001		01.01.2003		01.01.2005
≥ 0.3 W and < 15 W		1.0 W		0.75 W		0.30 W
≥ 15 W and < 50 W		1.0 W		0.75 W		0.30 W
≥ 50 W and < 75 W		1.0 W		0.75 W		0.30 W

1. Compliant with European Code of Conduct on Efficiency of External Power Supplies, phase 2, 01.01.2003

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