TPS6735EVM is an evaluation board for DC/DC and AC/DC (off-line) SMPS (Switch Mode Power Supply). The board converts a wide input voltage range between 9V and 45V into a fixed 5V output. It features built-in microcontroller, LCD, and demo design code that enable evaluation of the TPS6735. The board serves as an ideal platform to evaluate, control, and optimize the performance of a switch mode power supply.

The board is designed with two channels: one dedicated to the primary side and one dedicated to the secondary side of the power supply. A MSP430 MCU on the primary channel provides an interface to the user. It allows for controlling and monitoring of the switch mode power supply via I2C interface. The user can also program the MCU via USB interface. The board also features an LCD panel connected to the MCU that displays real-time parameters and environmental conditions.

The working principle of the TPS6735EVM comes into play when an AC or DC input voltage is supplied to the board. The TPS6735EVM can be powered. Any voltage between 9V and 45V can be supplied from a wound or bridged transformer to the board and the voltage will be transformed into a constant 5V output voltage. This is done by the MSP430 MCU controlling the primary side MOSFETs of the switch mode power supply. When the output voltage reaches the set voltage, the MCU will reduce its output and maintain the constant 5V across the output.

The TPS6735EVM can support a wide range of input voltages from 9V to 45V AC or DC, allowing the user to choose the best option for his application. The board has a very low quiescent current which will help prolong the life of the board as well as reduce the overall power consumption in applications that require low power consumption. The board is also able to withstand high ambient temperatures up to 125°C, which is necessary for applications in harsh industrial environments.

The board is perfect for testing and evaluating switch mode power supplies ranging from 1V to 45V and providing constant 5V output. The board is also great for evaluating power converters designed for use in automotive, industrial, telecom, networking, and consumer applications.

The TPS6735EVM is a great platform for evaluating, controlling, and optimizing switch mode power supplies. Its features such as wide input voltage range, low quiescent current, and high ambient temperature operation make it an ideal board to evaluate SMPS in a wide range of applications. The board can also be used to create custom switch mode power supplies tailored to the application’s requirements.
