ADP2302-EVALZ

ADP2302-EVALZ is a serial evaluation board for offline DC/DC and AC/DC Switch Mode Power Supplies. It is a complete switch mode solution for evaluating the performance of the ADP2302, a feature-rich quasi-resonant power switch controller IC. The ADP2302-EVALZ incorporates the ADP2302 quasi-resonant power switch and provides peripherals for monitoring, reporting, and controlling power and port signals. The evaluation board is a fast, cost efficient, and convenient way to evaluate the performance of the ADP2302.

DC/DC and AC/DC power supplies are widely used for many different applications, ranging from computers and consumer electronics, to communication and industrial products. The ADP2302-EVALZ allows designers to rapidly prototype the ADP2302 power switch controller. It can be used for powering any device that produce a DC or AC voltage output.

ADP2302-EVALZ Working Principle

The ADP2302-EVALZ evaluation board is designed to evaluate the ADP2302 quasi-resonant power switch controller. The board utilizes the ADI PWM controller, ADP2302, and offers step-by-step instructions for prototyping the PWM controller. The evaluation board is designed to control and regulate the switch-mode DC/DC or AC/DC power supply outputs. The ADP2302-EVALZ supports quasi-resonant and burst-mode operation. The primary active devices in the board are all surface mounted along with connectors for interfacing with the power source and power load.

The board is provided with three modes of operation. In the first mode, the board is controlled via manual switches and the oscilloscope. In the second mode, the board can be controlled via external control signals. In the third mode, the board can be controlled via a dedicated microcontroller. The board provides a low voltage input for powering the microcontroller, as well as additional voltage levels which can be used to supply additional power to external devices.

The board is provides ADC pins for current monitoring and temperature sensing, provide frequency compensation for the ADP2302, and also provide a power export terminal for connecting to a capacitive filter. The ADP2302-EVALZ also includes a power switch protection circuit. This protection circuit automatically switches off the output when the supply current for the ADP2302 exceeds its rated value, protecting the ADP2302 from potential damage.

The board is also equipped with a soft-start circuit for controlling the rise and fall times of the output and a sleep mode for saving power during idle mode. The ADP2302-EVALZ also provides two LED indicators which can be used to show the current power status or signal emergency events.
