TPS75233QPWPG4

Overview

The Texas Instruments TPS75233QPWPG4 device is a low-power voltage regulator with 1.1 A peak output current, specifically designed for automotive applications. This device operates with a 1.8 V to 5.5 V input voltage range and has an adjustable output voltage range of 0.575 V to 5.25 V. It is available in the 10-pin QFN package.

Working Principle

The TPS75233QPWPG4 device operates with a 1.8 V to 5.5 V input voltage range and has an adjustable output voltage range of 0.575 V to 5.25 V. It is configured to be a low power, low noise linear regulator which can provide up to 1.1 A peak output current.

Its operation is based on a two-stage architecture that merges an initial step-down switching regulator stage with a subsequent low dropout (LDO) linear regulation stage. This two-stage regulation optimizes the amount of energy needed for each stage, and combines the fast transient response of a switching converter with the low output noise of a linear regulator.

The switching regulator stage consists of a high frequency PWM controller to ensure reliable and low noise supply power, while the low-dropout linear regulator stage provides the post-regulation necessary for load stability. In addition, the TPS75233QPWPG4 device is integrated with thermal protection circuitry which ensures safe operation within the operating temperature range.

The device also has additional features such as power good flag and sleep mode, which allow better thermal performance. It also has a wide frequency range and low current consumption, providing a cost-effective solution for automotive applications.
