It is mainly designed for fast switching (<1µS on/off) in the high frequency range of 20KHz to 200KHz. Moreover, the cellular device and RF applications, as well as the battery powered applications are also easily addressed with the TPS55332QPWPRQ1.

Some of the use cases of the TPS55332QPWPRQ1 include portable power solutions, voltage conversion solutions, mobile charging solutions, AC/DC supplies, low noise DC-DC solutions, battery powered solutions, etc. This versatility makes the TPS55332QPWPRQ1 applicable to various applications and introduces the integrated MOSFET controller to enable smarter designs.

Working Principle

The TPS55332QPWPRQ1 is based on a voltage regulator architecture with synchronous switches, DC bias current control and an input voltage range of 5 - 28 VDC. It is capable of delivering up to 30 W of output power to a single output. The main elements of the TPS55332QPWPRQ1 solution are the integrated set of controllers and MOSFETs, which together provide a high level of performance and reliability.

For the input voltage range, the TPS55332QPWPRQ1 uses two transistor based feedback loop for controlling the output voltage and its accuracy. This provides stable output voltage over a wide range of input supply conditions. It is also capable of automatically adjusting the switching frequency to provide localized ripple and noise suppression. The voltage regulation loop can be configured in either linear or switching mode.

In order to reduce power dissipation, the TPS55332QPWPRQ1 uses synchronous rectification and secondary-side synchronous FETs. This technique offers a much higher efficiency compared to the conventional non-synchronous rectification, enabling lower power dissipation and allowing for a much smaller solution size.

To make use of the integrated MOSFETs, the TPS55332QPWPRQ1 also features a PFM mode, which offers high efficiency at light load current. It operates by minimizing the number of switching cycles, thus minimizing the switching losses and increasing the output current efficiency at light load.

The TPS55332QPWPRQ1 also provides high speed Reverse Current Protection (RCP), eliminating the need for an external rectifier in the input circuit. This feature prevents the back flow of current in the event of input voltage exceeding that of the output.

Overall, the TPS55332QPWPRQ1 provides a highly optimized and robust solution for dc-dc conversion, and is suitable for various applications due to its high performance, efficiency and small form factor. The product offers excellent compliance with EMC and safety standards, making it an excellent choice for energy-sensitive and motion control applications.
