Application Note

The SPD series of modules are designed as embedded isolated PoE PD solutions. SPD modules are fully integrated, thin type and high DC/DC converting efficiency PD modules.

The SPD modules are compliant with IEEE 802.3af power classification, Class 0 to Class 3, signature and support PSE Alternative A and Alternative B connections. Maximum power output can reach 12W (SPD-12, 89% DC/DC efficiency@ full load). Tiny size, 60mm (L) x 16.9mm (W) X16mm (H), wide input voltage range, 37Vdc to 55Vdc and less external components needed one output decoupling capacitor. The operating temperature is from -15oC to 55oC, @ Full load.

SPD modules support two different output voltage modules - 5Vdc and 12Vdc. SPD modules follow the design concept of TPD and THPD modules, using multi-layer ceramic capacitor (MLCC) only, to avoid instability even malfunction issue within long-time operation or higher temperature condition. And SPD modules are also pin to pin compatible with TPD modules.
