Application Note

The PDI series of modules are designed as embedded isolated PoE PD solutions for extended working temperature environment (-40°C ~ +85°C). They can support a reliable and stable PoE application in critical conditions, like higher temperature fields, the sealed housing, enclosed type devices, …etc.

The PDI modules are fully integrated, less thermal accumulation and high DC/DC converting efficiency PD modules, PDI-12 is 92% DC/DC converting efficiency @ full load; PDI-50is 89% DC/DC converting efficiency @ full load. Tiny size, 60mm (L) x 16.7mm (W) X16mm (H) and less external components is needed, one output decoupling capacitor.

PDI modules support two different output voltage modules – PDI-50 (12W / 5Vdc) and PDI-12 (12W / 12Vdc). The PDI modules are also designed to pin to pin compatible with TPD and SPD modules. All capacitors on module are MLCC equipped only to reduce the risks coming from the failed EC capacitors.
