The TPS84610EVM-003 evaluation board is an ideal tool for evaluating the performance of the TPS8461x synchronous rectified buck converters. This board is designed for DC/DC & AC/DC (Off-Line) SMPS applications. It operates from an input voltage of 18V to 60V DC and offers up to 14A load current, based on the selected part and VIN. It is capable of delivering an output voltage that can be programmed from 0.85V to 5.5V.

The TPS84610EVM-003 evaluation board is designed to minimize external components while offering maximum flexibility when evaluating the TPS8461x synchronous rectified buck converters. It features adjustable voltage output and includes an output voltage sequence control function. In addition, the board offers allow sequencing the on and off times for each of the two output voltages. The adjustment of the MOSFET drive strength is also included on the board.

On the TPS84610EVM-003 evaluation board, the TPS8461x synchronous rectified buck converter is configured for use with two external MOSFETs. The MOSFETs are chosen based on their on-resistance and its ability to support the required output power and thermal budget. The two MOSFETs are mounted on the board with its source connected to the converter ground and its drains tied together and connected to the output filter capacitor. A bootstrap diode is also included for increased efficiency.

The board includes protection features such as output over-voltage protection (OVP), output over-current protection (OCP), short-circuit protection (SCP) and thermal shutdown (TSD). The board also includes an output voltage soft-start function, which helps prevent inrush current when the output voltage is rapidly changed. The OTP feature can be enabled by adding a discrete resistor to the board.

The TPS84610EVM-003 evaluation board is an excellent tool for evaluating the performance of the TPS8461x synchronous rectified buck converters. It offers flexibility in evaluating and setting the output voltage, MOSFET drive strength, output voltage sequence, and many other parameters. The board includes protection features and on-board MOSFETs, which allows the user to evaluate the performance of the TPS8461x in a variety of applications.
