EVAL-CN0342-EB1Z

EVAL-CN0342-EB1Z is a CN0342 circuit evaluation board. The circuit is an isolated, flyback power supply that uses a linear isolated error amplifier to supply the feedback signal from the secondary side to the primary side. Unlike optocoupler-based solutions, which have a nonlinear transfer function that changes over time and temperature, the linear transfer function of the isolated amplifier is stable and minimizes offset and gain errors when transferring the feedback signal across the isolation barrier. The entire circuit operates from 5V to 24V, allowing it to be used with standard industrial and automotive power supplies. The output capability of the circuit is up to 1A with a 5V input and 5V output configuration. This solution can be adapted for use in applications where higher DC input voltages are used to create lower voltage isolated supplies with good efficiency and a small form factor.
