TPS51623RSMR Application Field

The TPS51623RSMR is ideal for applications such as automotive, industrial and enterprise computing, networking, storage and other high-temperature and high-performance applications. It can also be used in high-temperature automotive, military and aviation systems, industrial motor controls, dynamic RAM (DRAM), and other medical and industrial applications. It is capable of providing up to 75A of output current at a range of output voltages.

TPS51623RSMR Working Principle

The TPS51623RSMR is a buck-converter IC with voltage-mode control, which means that it attempts to maintain a constant output voltage. This is achieved by regulating the duty cycle of a power switch, so a higher output voltage results in a higher duty cycle and a lower output voltage results in a lower duty cycle. It also uses synchronous rectification, which means that the output voltage is derived from a high-frequency switching waveform, and is more efficient than asynchronous rectification. This enables the TPS51623RSMR to maintain a constant output voltage, even under varying loads.

The TPS51623RSMR also has numerous protection features, such as over-voltage, over-current, under-voltage, and over-temperature protections that ensure safe and reliable operation. It also includes an integrated MOSFET, which eliminates the need for an external voltage regulator. Finally, the TPS51623RSMR’s high-frequency operation minimizes its size and allows it to be used in tight spaces, making it an ideal choice for when space is a premium.

Conclusion

The TPS51623RSMR is an excellent choice for applications such as high-temperature and high-performance systems, automotive and industrial motor controls, dynamic RAM (DRAM) and other medical and industrial applications. Its voltage-mode control and synchronous rectification enables it to maintain a constant output voltage, even under varying loads.
