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.

Evaluation Boards

Ag7300 Evaluation Board

 EvalAg7300 are intended for testing and evaluation of the Ag7300 DCDC converter modules. Ag7300 provides a regulated 55V DC output. The evaluation boards can be used in conjunction with an EvalAg6800 to produce a isolated single port IEEE802.3BT type 4 PSE from a 18 – 36V supply . Please use the links provided to order boards or download the user manual.
NOTE : Evaluation Boards are supplied pre-loaded with a sample module.
