The SP6134EB evaluation system enables users to evaluate the performance of the integrated circuit of a DC/DC and AC/DC offline SMPS. It is an off-line switch-mode power supply (SMPS) test system for use in OEM laboratories, and power electronics laboratories. The system consists of an evaluation board, a power supply, a power meter, optional current meters, a LED load board, and a PIC microcontroller development board.

The evaluation board contains a SP6134EB IC, which is a high density, high efficiency, and low-cost AC/DC Offline SMPS PCBA. The SP6134EB IC combines all the power-management functions into one device. The device includes an output voltage control loop, a soft start/soft stop function, an over voltage protection circuit, an over load protection circuit, a short- circuit protection circuit, an over temperature protection circuit, and an on/off control circuit. The evaluation board contains the necessary components for the SMPS control such as resistors, capacitors, and diodes. The evaluation board also provides the necessary interfacing for the user\'s PC or PIC microcontroller development board.

The SP6134EB IC is used in off-line applications such as lighting systems, electric drives, appliances, battery chargers, welding power supplies, vacuum cleaners, computer power supplies, etc. It is ideal for those applications that require high-density, high-efficiency, and low-cost SMPSs. The IC supports an operating frequency up to 20kHz. The integrated input voltage range is from 150 to 400V, making it suitable for a wide range of input sources. The evaluation board allows the user to test the IC performance with different input sources. The board also contains a current-limited output stage, making it safe to use in the development stage.

The SP6134EB evaluation board operates in either open-loop or closed-loop mode; the user can select the mode based on the application requirement. The open-loop operation mode is used for applications requiring a constant output voltage and current. The output voltage and current can be adjusted by using the on-board potentiometers. The closed-loop operation mode is used for applications requiring a variable output voltage and current. The board has an input voltage monitor so that the operating parameters can be easily adjusted for different input sources.

The power supply and power meter provided with the system can supply the required input voltage and measure the output voltage and current. The LED load board can be connected to the system to simulate a load. The PIC microcontroller development board can be used for real-time monitoring and logging of the IC parameters. This allows the user to monitor and log the operating parameters of the IC in real-time. This also makes the evaluation easier, faster, and more comprehensive.

The SP6134EB evaluation board is ideal for those applications that require high-density, high-efficiency, and low-cost off-line SMPSs. It is a perfect system for OEM laboratories, power electronics laboratories, and educational and research environments that require evaluation and prototyping for AC/DC offline SMPS applications.
