PMIC - Voltage Regulators - Linear

The TPS70258PWPR is a very versatile and dependable voltage regulator for a wide range of applications. It is a PMIC (Power Management Integrated Circuit) voltage regulator with linear technology, designed for both commercial and industrial use. The TPS70258PWPR is capable of regulating 1.8 V to 5.0 V with an input voltage range from 0.8 V to 5.5 V. The output voltage is adjustable according to the application needs, offering flexibility and performance in a wide variety of applications, such as precision voltage reference, voltage conversion and battery management.

The TPS70258PWPR contains several features, allowing it to fulfill its purpose and be suited for a number of applications. These features include an adjustable current limit, an enable/disable function, input overvoltage protection, output overvoltage protection and an adjustable soft-start. Additionally, the PMIC incorporates advanced safety features, such as thermal shutdown protection, output over voltage amplifier protection, over-temperature shut-down protection and under-voltage lockout.

Working Principle

The TPS70258PWPR utilizes a voltage reference source, which is between the input and the output. The supply voltage finds its way through the feedback loop to the reference, which is then fed to the control circuitry. The control circuitry adjusts the gate voltage of the power switch accordingly, achieving the desired output voltage. When the output voltage equals the reference voltage, the gate voltage is adjusted to maintain the desired output voltage. In order to maintain efficiency the minimum insulation resistance of the output should be less than 100m of power switch, which is inside the system.

The input voltage, the output voltage and the current are monitored and regulated by means of an adjustable current limit and overvoltage protection circuit. As soon as the input voltage drops below the overvoltage protection threshold, the TPS70258PWPR will shut down. Furthermore, the output voltage and current are monitored by the adjustable current limit and overvoltage protection circuits.

Applications

Due to its versatility, the TPS70258PWPR can be applied to a wide range of applications. Some of these applications include: portable dimmable LED lighting, high efficiency DC/DC converters, battery applications, tablets and notebooks, augmented reality/virtual reality headsets and industrial automation equipment.
