Introduction to TPS563219EVM-663

TPS563219EVM-663 is an evaluation module designed to focus on the features and performance of the TPS563219 synchronous monolithic buck controller from Texas Instruments (TI). This evaluation module is designed to work with a wide range of off-line switching power supplies in DC/DC and AC/DC applications.

Applications of TPS563219EVM-663

The TPS563219EVM-663 is used as an evaluation module for the TPS56321x family of synchronous buck controllers, as well as other similar controllers that can work with it in its target application power supply designs.The TPS563219EVM-663 serves as an ideal evaluation module for designing point-of-load power supplies. These are supplies that are used in embedded systems, electronics, vehicle power systems, medical equipment, and other applications.The output of the evalution board supports up to 600V DC output voltage, and 500mV ripple at the output. The peak current should not exceed 3A at the output, while maximum switching frequency should not exceed 500kHz. The board can operate in short circuit, open loop, thermal overload and UVLO conditions.

Working principle of TPS563219EVM-663

The TPS563219EVM-663 works by using a combination of voltage modulation and voltage feedback. It uses a voltage-modulated switch to control how much power is drawn and delivered to the output stage.The first step in the process is the voltage reference. This is an analog signal with a specific voltage level that is used to control the voltage sent to the output stage. The voltage reference is then compared with the feedback from the output stage to see if the output voltage is too high or too low.Next, the output voltage is sent through the voltage-modulated switch which then either increases or decreases the power being drawn. This process is then repeated until the output voltage is within an acceptable range of the voltage reference.Finally, the board checks that the output voltage is stable, as well as any short circuit, open loop, thermal overload, and under-voltage lockout conditions.

Conclusion

The TPS563219EVM-663 is an evaluation board designed to work with a variety of off-line power supply applications. The main features of this board are its ability to control and regulate the output voltage with voltage modulation and feedback, as well as supporting conditions such as short circuit, open loop, thermal overload, and under-voltage lockout protection. The evaluation board is ideal for embedded systems, electronics, vehicle power systems, medical equipment, and other applications that require efficient and reliable point-of-load power supplies.
