The Ag7300 is a high power DC/DC boost converter, designed to generate the higher voltages whilst providing the isolation required for an IEEE802.3 compliant PSE application. For use in single IEEE802.3bt (PoE++) applications, multiple IEEE802.3af/at (PoE/PoE+) applications or power distribution applications.
The Ag7300 accepts a wide DC voltage input range, from 18V to 36V, and provides a regulated adjustable output of between 48V to 57V, while achieving greater than 91% efficiency. The DC/DC converter also has built-in output overload, output short-circuit and over-temperature protection.

Ag7300 Evaluation Board
EvalAg7300 are intended for testing and evaluation of the Ag7300 DC/DC boost converter modules. Ag7300 provides a regulated 55V DC output. The evaluation boards can be used in conjunction with an EvalAg6810 to produce a isolated single port IEEE802.3bt type 4 PSE from a 18V-36V supply. Please use the links provided to order boards or download the user manual.
