Application Note

Description:
The AHPD module is designed as an embedded isolated and advanced PoE⁺ (IEEE802.3at compliant) PD solution. AHPD module is fully integrated and ultra high DC/DC converting efficiency (92% @ full load condition) PD module. AHPD improves thermal effect more efficiently and power saving that is caused by its ultra high DC/DC converting efficiency.

The AHPD module is compliant with IEEE 802.3at power classification (type 1 and type 2), Class 0 to Class 4 signature and support PSE Alternative A / B connections. Maximum output power can reach 25.5W (12V/2.125A). Maximum peak output power can be up to 30W (12V/2.5A). The size is 75mm (L) x 30mm (W) X15.5mm (H), input voltage range is from 37Vdc to 60Vdc and less external components, only one output decoupling capacitor is needed. Operating temperature range is from -25^oC to 70^oC, @ Full load.

AHPD module is designed by a more advanced concept to reach higher efficiency reliability, and AHPD module has same pin definition with THPD module.
