Description
PSE applications that deliver both power and data over ethernet to devices such as IP cameras and wireless access points require compact, efficient, and standards-compliant solutions to support increasing power demands. This reference design's wide input voltage range of 9-48V ensures compatibility with diverse and common power sources (12V/24V/48V). Its active clamp topology achieves efficiency greater than 90% at 100W of power and nominal Vin conditions. The standard half-brick form factor (2.3in x 2.4in) enables easy integration, and the strong isolation (2200Vac) provides superior industrial protection and safety.
