15 Output Current Production Distribution
Figure 82 shows the production distribution of output current for 267 RD251 boards. The
data was gathered using a NH Research 5600 series power supply test system,
commonly used in the power supply industry for production testing of power supplies.
The data is also summarized in table 6.
Measurements were made at room temperature, V
VAC and 230 VAC. This distribution includes variations not only from the LinkSwitch-PL
devices but also all the components of the driver.
From the data it can be seen that the output current could be centered slightly
(-1.9% at 115 VAC) to achieve the 350 mA nominal output current by adjusting the output
current sense resistor value. Therefore to correctly demonstrate the achievable tolerance
of the design, C
