TPS54040ADGQR Typical application Circuitry

TPS54040ADGQR

The TPS54040ADGQR is a step-down (buck) regulator offered by Texas Instruments. It is characterized by its low power consumption, high efficiency and its ability to work over a broad input voltage range of 4.5 V to 42 V. This makes it an ideal component in power supply designs for various applications such as automotive, industrial and power modules.

Here's an outline of an application circuit for the TPS54040ADGQR, highlighting four key aspects:

1. Power Supply: The TPS54040ADGQR requires an input voltage range of 4.5V to 42V. A decoupling capacitor should be connected between the VIN (input voltage) and PGND (power ground) pins to provide a stable power supply.

2. Feedback Resistors: A resistive divider connected to the output voltage feeds back to the FB pin, allowing the device to regulate the output voltage. The resistor values are chosen based on the desired output voltage and the feedback voltage specified in the datasheet.

3. Inductor and Output Capacitor: The inductor and output capacitor form an LC filter for the output. Based on the desired output voltage, switching frequency, and load current, their values are selected. The inductor is connected to the SW pin, and the output capacitor is connected to the output voltage and ground.

4. Frequency Setting Resistor: A resistor connected to the RT/CLK pin sets the switching frequency of the regulator. Based on the desired frequency listed in the datasheet, the resistor value is selected.

This is only a general recommendation for a TPS54040ADGQR application circuit, so keep that in mind. The specific circuit design will vary depending on the requirements of your application. Therefore, always refer to the TPS54040ADGQR datasheet and relevant Texas Instruments' technical resources for comprehensive circuit design information.
