Introduction

The Texas Instruments TPS7A7200EVM-718 Evaluation Board is a linear voltage regulator circuit designed to operate over a wide range of input voltages and provide up to 1 A of continuous output. The TPS7A7200EVM-718 is based on an internally compensated, low output voltage, low parts count approach with an adjustable output voltage to accommodate various applications. The adjustable output voltage capability, along with the wide range of input voltages, makes it an ideal choice for many different application fields.

TPS7A7200EVM-718 Description

The TPS7A7200EVM-718 is a high-performance low-noise, low-drift linear voltage regulator that is capable of up to 1 A of continuous output current. The TPS7A7200EVM-718 has a very wide input voltage range from 2.7 V to 18 V, with a continuously adjustable output voltage from 0.8 V to 10 V. The TPS7A7200EVM-718 is capable of providing low output voltage and low dropout voltage, and is internally compensated for stability and transient response. The board offers both an adjustable and a fixed output voltage in addition to programmable output voltage ramping.

Applications

The TPS7A7200EVM-718 is an ideal choice for applications where low dropout operation and adjustable output voltage are required in nominal 2.7 V to 18 V input voltage range. It is well suited for low voltage applications such as instrumentation, industrial, test equipment, medical ultrasound imaging and other industrial applications.

Working Principle

The TPS7A7200EVM-718 linear voltage regulator works on the principle of controlling the output voltage by using a feedback loop. When the output voltage is below the set value, the reference voltage at the input of the circuit increases, triggering the N-channel MOSFET transistor switch to turn on and deliver current to the output of the circuit. This increases the output voltage until it reaches the set value. As the output voltage rises, the reference voltage also decreases and the N-channel MOSFET transistor switch begins to turn off which reduces the current delivered to the output of the circuit.

Conclusion

The TPS7A7200EVM-718 Evaluation Board from Texas Instruments is an ideal choice for applications where low dropout and adjustable output voltage are needed. Its wide input voltage range and continuously adjustable output voltage make it an excellent choice for many different application fields. Its internal compensation and low parts count results in excellent stability and transient response.
