Nexperia NXF6505B

Description

The NXF6505B evaluation board enables the evaluation of Nexperia's NXF6505B - a low noise, 1.2 A push-pull transformer driver for isolated power supplies. The EVB can provide the isolated power supply with one positive output voltage. For easy evaluation of this EVB, the test points are added to measure the circuitry voltages.
