PM6686 Application Field and Working Principle

PM6686 is a special purpose voltage regulator from Texas Instruments, developed for industrial manufacturing and computing systems application development. It uses precision voltage control for power regulation, used for components such as processors, memory, sensors, and more.

Uses of PM6686

The PM6686 is a precision voltage regulator designed for use in industrial systems. It is designed to regulate power and provide highly efficient, tightly controlled supply voltages throughout the system. The PM6686 offers accurate voltage control and output ripple rejection, making it an ideal choice for applications in computing and industrial systems such as motor control, power supply design, and the various levels of power management in the automation industry.

The PM6686 supports many operating system and power consumption requirements. It can easily regulate between 9.6V and 24V, and output voltages that range from 0.8V to 18V. This makes the PM6686 a suitable choice for applications that require both low and high voltage supply, as well as for applications that require a large voltage range.

The PM6686 is designed to provide high efficiency and precision voltage control, even under highly variable conditions. Its output ripple is reduced by high loop bandwidth and advanced compensation techniques, making it capable of operating in harsh conditions such as high temperatures, high vibration frequencies, high load transients, and sudden stop events.

Features of PM6686

The PM6686 offers a wide array of features, giving it the versatility to operate in any industrial system. Its voltage regulator module (VRM) loaded rail-to-rail output allows for fully adjustable amplitude and phase range, both in the form of phase length and voltage amplitude. This allows for the engineering of a perfectly tailored power solution for the given application.

The PM6686 also features a Current Limit Control feature, which is adjustable from 5A to 25A. This allows for higher reliability and safety, as the current limit can be set to protect any device from over current protection. Additionally, the PM6686 features over voltage, under voltage, and over current protection, all of which are adjustable via external hardware, ensuring that the device won’t be damaged due to excessive voltage or current.

Finally, the PM6686 supports a wide temperature range, making it suitable for operating in extremely cold or hot environments. This makes it an ideal choice for industrial systems, as they often have to operate in harsh conditions such as outdoors, in extremely hot or cold climates, or in other tough to manage environments.

Working Principle of PM6686

The PM6686 works by taking the input signal and converting it into a precisely regulated output voltage. This is done by using a voltage feedback loop with a voltage reference, which is fed back to the PM6686\'s output stage. This loop controls the output voltage, adjusting the voltage and amplitude of the signal to maintain the set voltage level.

The voltage regulator module (VRM) in the PM6686 is a key component in its functionality. The VRM compares the input voltage to the user-manually adjusted output voltage and adjusts the output voltage to maintain the specified level. The VRM also offers an adjustable current limit to protect the output stage from over current.

The PM6686 also includes a slew rate control circuit and thermal protection, both of which can be used to reduce unwanted ripple and reduce power consumption. The slew rate control circuit adjusts the output signal when the input voltage is changing in order to reduce undesirable output ripple, while the thermal protection circuit adjusts the output voltage and enables the PM6686 to cool itself when the temperature gets too high.

Conclusion

The PM6686 is a precision voltage regulator designed for application in industrial systems. It offers high efficiency and precision voltage control, even under highly variable conditions. Its versatile features allow it to be used in a wide variety of applications, such as motor control, power supply design, and various levels of power management in the automation industry.

The PM6686 is an excellent choice for applications that require a high level of precision, as well as for applications that require a large voltage range. Its adjustable current limit, over voltage, under voltage and over current protection, and its wide temperature range make it a perfect choice for any demanding industrial system.
