PMIC (Power Management integrated Circuit) are indispensable components in today\'s electronics. Voltage Regulators hold a special place in this family, as they provide a stable source of power for electrical components operating under a wide range of conditions. Among them, linear voltage regulators provide the most reliable and efficient means for regulating a circuit’s supply voltage. The TLV70718PDQNR is a voltage regulator from the TLV707 series of linear regulators from Texas Instruments that provides an incredibly high level of performance and features. In this article, we will discuss the application fields, working principle, and features of the TLV70718PDQNR.

Application fields

The TLV70718PDQNR is primarily designed for applications such as motor control, gate drivers, motor drives, Switched Mode Power Supplies (SMPS), and high power conversion applications where high accuracy of regulation is required. It provides a highly efficient and reliable voltage reference that enables current sensing accuracy of up to 40mA with 0.5% accuracy over the entire temperature range (operates up to 125°C). This makes it ideal for high-precision, high-power applications, such as motor control, gate drivers, and motor drives, where quick, on-the-spot voltage references are required.

Working Principle

The TLV70718PDQNR operates on the principle of a Buck Converter. It functions as a voltage regulator that takes an input voltage, regulates it, and gives a stabilized output voltage. This regulated output voltage is given as a reference, giving the user the freedom to select the output voltage. The TLV70718PDQNR has a wide input voltage range, which allows it to be used with a wide variety of input sources. This Buck Converter works by switching the input voltage to a lower level, passing it through an inductor, and increasing it to the desired output voltage.

The TLV70718PDQNR regulates the output voltage by monitoring the input voltage and adjusting the duty cycle of the switching cycle. The regulation process is managed by a comparator that measures the output voltage and compares it with the desired reference voltage. If the output voltage is lower than the reference voltage, the duty cycle of the switching is increased, otherwise, it is decreased. This process is repeated continuously to ensure that the output voltage is maintained at its desired reference voltage.

Features

The TLV70718PDQNR has a variety of features that make it an ideal choice for controlling high-power and current applications. It has an effective over-temperature protection and current limiting protection to protect itself from damage due to environmental conditions. It can operate up to the input voltage of 36V and can handle up to a maximum load of 5A. It also possesses a low quiescent current and has a wide operating temperature range of -40°C to 125°C, making it perfect for high-temperature applications. Additionally, it has an efficient and accurate voltage regulation with up to 0.5% accuracy of regulation over the full temperature range. As such, the TLV70718PDQNR is a highly efficient and reliable voltage regulator for a variety of applications.

In conclusion, the TLV70718PDQNR is an ideal solution for applications requiring a high-performance, reliable, and accurate voltage regulator. It is a great option for motor control, gate drivers, motor drives, Switched Mode Power Supplies (SMPS), and high power conversion applications due to its wide input voltage range, high output current capability, and highly accurate voltage regulation. With its features such as effective over-temperature protection, current limiting protection, and wide operating temperature range, the TLV70718PDQNR is an excellent choice for anyone looking for an efficient and reliable voltage reference.
