Introduction to the TPS25741AEVM-802 Evaluation and Demonstration Board

The TPS25741AEVM-802 Evaluation and Demonstration Board (EVM) is a quick, easy and cost effective way to evaluate the Essential Power MOSFET. The EVM is designed to demonstrate the performance, application field, and working principle of the TPS25741, a single-channel high-side MOSFET switch. The TPS25741 operates from 1.6V to 5.5V for a wide range of applications. It features a typical on-resistance of 0.3Ω in a SOT23-6 package.

Application Field

The TPS25741AEVM-802 is useful for applications that require high efficiency power switching, such as DC/DC converters, consumer electronics, and small appliances. This particular board is especially suited for applications with products requiring small form factors and low power consumption.

Working Principle

The TPS25741AEVM-802 board features a single-channel, high-side power MOSFET switch. The principle behind this is the simple concept of applying a voltage across a MOSFET, switching it on and off. The FET is usually on when its voltage is higher than its gate voltage, and off when its voltage is lower than its gate voltage. The EVM demonstrates how this works by using the TPS25741, a n-channel MOSFET with an integrated gate driver circuit and protection features. The TPS25741AEVM-802 board provides a 5V input to the TPS25741 via an onboard power regulator. This power is then delivered to the gate driver circuit which in turn drives the gate voltage of the MOSFET. The gate driver applies an inverted voltage to the gate of the switch, effectively switching it on and off depending on the input signal applied to its gate voltage.

Conclusion

The TPS25741AEVM-802 Evaluation and Demonstration Board is an ideal tool for evaluating, prototyping, and demonstrating the performance, application field, and working principle of the TPS25741 Single-channel High-Side MOSFET Switch. It provides an easy way to experiment with sample circuits, as well as to measure power consumption and efficiency.
