TPS54900PWG4 Application Field and Working Principle

The TPS54900PWG4 is a Single-Phase, six-pin synchronous, non-isolated, step-down DC/DC regulator, which is designed for computing, communications, and industrial systems. It is optimized to provide up to 12 A continuous output current with a wide input voltage range of 3.2 V to 16 V. The device provides three user-configurable outputs to regulate three different voltages. The programmable current limit and thermal shutdown with external NTC thermistor make them safe and reliable in a variety of applications. The TPS54900PWG4 is available in a Tiny Green 6-Pin WSON package.

Applications

TPS54900PWG4 is suitable for a variety of applications, such as computing and communications systems, industrial systems, sensors nodes, parallel battery stack and multiple rail designs, as well as automotive solutions. The TPS54900PWG4 can be used for powering CPUs, GPUs, FPGAs, DSPs, SoCs, memory, PCIe, and other loads in a computing system. It is also used for powering other load managing systems in communications and industrial systems.

Working Principle

The TPS54900PWG4 is a synchronous, step-down DC/DC regulator that contains an integrated power switch, integrated power diode, and a voltage adjustment amplifier. The internal power switch is controlled by an internal circuit, while the integrated power diode carries the power from the input to the output stage. The integrated voltage adjustment amplifier allows for programmable over/undervoltage regulation of the output voltage. The device also provides programmable current limiting and thermal protection to prevent damage to the power supply or system. The TPS54900PWG4 also provides spread spectrum frequency modulation, which reduces system noise and EMI. The device is available in a Tiny Green 6-Pin WSON package.

Conclusion

The TPS54900PWG4 is an advanced single-phase, six-pin synchronous, non-isolated, step-down DC/DC regulator that is designed for a wide range of applications. It provides three user-configurable outputs to regulate three different voltages, programmable current limit and thermal shutdown, and spread spectrum frequency modulation for reduced system noise and EMI. The TPS54900PWG4 is available in a Tiny Green 6-Pin WSON package.
