The TPS54231EVM-372 is an evaluation board (EVM) built to examine the specifications and features of the TPS54231 low-noise synchronous buck regulator. This device is ideal for space-constrained, low-noise power supply applications, including personal computers, servers, local area networks, printers, and various types of consumer electronic devices. With a low-noise profile, the TPS54231 is ideal for powering sensitive analog circuitry.

The TPS54231EVM-372 is designed to allow users to easily evaluate the TPS54231. It features an adjustable output voltage with one external resistor, integrating circuits for ease of use, plus a compact form factor. The TPS54231EVM-372 can be set up to a standard PC power supply connector, allowing users to power a PC from the EVM. The TPS54231EVM-372 also features short-circuit protection and a modern controller with improved transient response.

The TPS54231EVM-372 is a DC-DC converter specially intended for applications requiring noise-free performance. It can be used for powering small, medium, and large-scale devices, as well as complex electronics. The efficient synchronous buck converter design of the TPS54231 eliminates noise and provides a steady flow of power. The EVM ensures low output voltage ripple at higher output currents without the need for additional input filtering and can generate an output voltage of up to 12V with up to 3A of current. Both components and highly efficient switching regulators handle a wide range of input voltages from 4.5V to 14V.

On the TPS54231EVM-372 board, there are control pins to configure the peak current indicator, or PCM signal, for either user-defined resettable operation or signal that indicates an overcurrent condition that does not need a reset. In the latter configuration, the device will switch off the output voltage after the overcurrent condition to limit the inrush current. Other features of the device include enable/disable options, external synchronization, as well as soft start, which helps control the output inrush current.

The working principle of the TPS54231EVM-372 is based on the TPS54231, which is a synchronous buck converter integrated circuit. This device performs pulse-width modulation (PWM) control of the output voltage. The power stage comprises a MOSFET switch, a low-side MOSFET switch, and a current sense amp. These components work together to convert the input voltage to the regulated output voltage. The input voltage is first connected to the high-side MOSFET and is sensed by the current sense amplifier. The low-side MOSFET is used to control the current, which is then regulated by the output voltage.

In addition, the TPS54231 also features an integrated power solution with independent voltage and current controls, enabling more efficient operation. The combination of an efficient power conversion circuit and a current sense amplifier make it possible to achieve very low output noise levels. Also, the wide input voltage range of 4.5 V to 14V and the adjustable output voltage range of 0.8 V to 12V make the TPS54231 a great choice for a wide range of applications.

The TPS54231EVM-372 is a great evaluation platform for the TPS54231. It boasts a number of features such as adjustable output voltage, short-circuit protection, enable/disable options, and synchronization which make the TPS54231EVB-372 a one-stop solution for a wide range of off-line switching applications.
