The LMZ31707EVM-002 evaluation board is a DC/DC & AC/DC (Off-Line) switch mode power supply (SMPS) solution. It can be used to evaluate the performance of the LMZ31707 high voltage integrated circuit (IC). The board operates with multiple output channels of a constant voltage output, providing a total output power of up to 500W. It is suitable for a wide range of applications, such as home appliance equipment, commercial instrumentation, industrial control, electric vehicles, LED lighting, and so on.

The LMZ31707EVM-002 board works by using PWM and pulse frequency control to regulate the output current. The circuit regulates the load by using two voltage feedback control loops. The inner loop feedback is a voltage feedback control which maintains the output voltage at the set point. The outer loop is a current feedback loop that maintains the output current. The SMPS circuit then switches the output transistor using a high frequency waveform. Using this waveform, it regulates the output current in response to load changes.

The LMZ31707EVM-002 is designed with high voltage high power operation in mind. The board includes a constant voltage output voltage range of 6V to 100V and a rated power up to 500W. It also has an efficiency of up to 93% and a power factor correction of up to 97%. The board also includes an adjustable soft start time to reduce power consumption at start-up and an adjustable over-voltage protection which provides further protection for the circuit.

The LMZ31707EVM-002 is equipped with many features to make it user friendly. The board includes an operating status LED display to indicate the system operating parameters in real-time. It also has an on-board potentiometer and display to adjust the voltage and current. There is also an on-board over-temperature protection and a DC output power failure detection function which can automatically reduce the power supply load when the output voltage is outside the normal range.

The LMZ31707EVM-002 is an excellent design solution for DC/DC & AC/DC (Off-Line) switch mode power supply applications. The board comes with a wide range of features to deliver efficient and reliable power supplies. Its high voltage and high power operation make it suitable for a wide range of applications, such as home appliance equipment, commercial instrumentation, industrial control, electric vehicles, LED lighting, and so on. The LMZ31707EVM-002 board is a highly reliable design solution which is ideal for today’s demanding power supply applications.
