Linear voltage regulators are an important part of any electronic system since they provide a reliable, cost-effective means to manage and regulate power supply. TPS79330YEQEVM is a specially designed voltage regulator for automotive applications. This evaluation board is designed to facilitate evaluation of the features and electrical performance characteristics of the device. In this article, we’ll discuss the application field and working principle of the TPS79330YEQEVM.

Application Field of TPS79330YEQEVM

The TPS79330YEQEVM is specifically designed for automotive applications such as vehicle infotainment systems, security systems, and powertrain control systems. It features 3-A output current and 2A peak current, and offers a wide input voltage range of 3.3V to 28V. The device is capable of operating over a wide temperature range from -40°C to +125℃. It is also designed to withstand a transient over-current of 8A and is protected against over-voltage up to 40V. Furthermore, it features an integrated output discharge functionality which protects against voltage build-up.

Working Principle of the TPS79330YEQEVM

The TPS79330YEQEVM is a step-down voltage regulator that regulates its output voltage according to a reference voltage. The device utilizes an internal PMOSFET to regulate the voltage. The voltage regulation is controlled by a feedback circuit that monitors the output voltage. The PWM control circuit then adjusts the duty cycle of the PMOSFET to maintain the output voltage at the desired level. The device also features an adjustable soft-start circuitry which limits inrush current during startup.

The device also features various protections such as over-voltage protection (OVP), over-temperature protection (OTP) and short circuit protection, which protect against damaging conditions. Additionally, it is also equipped with a load disconnect circuit which disconnects the load from the power supply when the output voltage drops below the preset limit. The device also features instantaneous current limiting which protects against overload conditions.

Overall, the TPS79330YEQEVM is a highly efficient and reliable linear voltage regulator, designed specifically for automotive applications. It offers a wide input voltage range, and features protections against damaging conditions. The device’s adjustable soft-start circuitry, over-voltage protection, and load disconnect functionality make it an ideal choice for automotive applications.
