The VSX60 Series are dual output converters with 18-36V and 36-75V input models with 3.3Vdc and 5Vdc outputs. The industry quarter-pak size of
2.3" x 1.5" x 0.5" coupled with 90% efficiency is an industry high-density breakthrough.
These converters utilize Vx high density technology. This technology has been featured in our highly efficient VKP and VKA series now successfully in use worldwide. The very high 90%

efficiency minimizes the requirement for heat-sinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX60 series feature virtually all of the options required by design engineers but not at the competition’s typical additional price for each option. This multitude of features are standard on the VSX60 series.

NOTES:
1. Marked with: specific model ordered, date
code, job code.
2. MATERIAL: Units are encapsulated in a low thermal resistance molding compound which has excellent chemical resistance and electrical properties in high humidity environments and over a wide operating temperature range. The encapsulant and outer shell of the unit have UL94V-0 ratings. Lead material is solder plated to allow ease of solderability.
3. IMPORTANT: When utilizing the PEM nuts for board mounting, it is required to follow guidelines in application note DCAN-40 available on the web at www.cdpowerelectronics.com.
