TLE4264GHTSA1 application field and working principle

TLE4264GHTSA1 is a linear voltage regulator from Texas Instruments. It belongs to the Power Management IC (PMIC) Voltage Regulators product family. It can regulate the input voltage with tight line and load regulation, as well as low output voltage noise in applications such as automotive, consumer and industrial. This voltage regulator includes features such as wide input voltage range from 8V to 30V, short circuit and over temperature protection, as well as a shutdown mode.

Working principle

The working principle of the TLE4264GHTSA1 is to bring down the input voltage to the desired output voltage by either buck or boost configuration. The input voltage is regulated through a series of voltage regulators, consisting of an error amplifier, an internal reference and a pass element. The error amplifier compares the output voltage to the reference voltage, generating an output current when the output voltage deviates from the reference voltage.

The pass element then regulates the input voltage and the output voltage according to the output current of the error amplifier. When the input voltage is higher than the output voltage, the TLE4264GHTSA1 operates in the buck configuration. In this configuration, the output voltage of the pass element is lower than the input voltage, resulting in a lower output voltage at the output end of the voltage regulator.

When the input voltage is lower than the output voltage, the TLE4264GHTSA1 operates in the boost configuration. In this configuration, the output voltage is higher than the input voltage, resulting in a higher output voltage at the output end of the voltage regulator.
