TPS53219ARGTR Typical application Circuitry

TPS53219ARGTR

The TPS53219ARGTR is a synchronous step-down controller from Texas Instruments, designed for powering single voltage rail ASIC, FPGA, DSP, and other processor-based systems. In ensuring that this component operates efficiently within your system, specific attention must be devoted to each pin and its function. Here are the instructions for connecting the TPS53219ARGTR correctly in your circuit:

1. Input Voltage (VIN): Pin 12 should be connected to your input voltage, which can range from 4.5V to 14V. Place a decoupling capacitor close to this pin to minimize voltage spikes.

2. Ground (PGND and AGND): Connect Pin 9 (PGND) and Pin 3 (AGND) to the system ground plane. The Power Ground (PGND) and Analog Ground (AGND) must be linked to the ground plane for the TPS53219ARGTR to operate without issues.

3. Feedback (VFB): Pin 5 receives the feedback voltage from the output through a resistor divider. Connect this pin to the point where the output voltage is being divided to ensure accurate voltage regulation.

4. Soft Start (SS/TR): Connect a capacitor to Pin 7 (SS/TR) to configure the soft-start time when the TPS53219ARGTR is enabled. This helps in gradual ramp-up of the output voltage, reducing inrush current.

5. Enable (EN): Use Pin 6 to enable or disable the TPS53219ARGTR. To enable and disable the device, respectively, connect this pin to a logic HIGH or LOW signal.

6. Switch Node (SW): Pin 11 is the switch node of the TPS53219ARGTR and should be connected to the drain of the high-side FET and the source of the low-side FET.

7. Bootstrap (BOOT): Pin 10 needs to be connected to an external bootstrap capacitor, which supplies the drive voltage for the high-side FET.

8. Current Sense (CS): Pin 8 (CS) is for sensing the inductor current. Attach this to a resistor for proper current sensing.

9. Power Good (PWRGD): Pin 4 provides an open-drain power good signal. You may connect this to a pull-up resistor to monitor the output voltage.

10. Frequency Set (RT): Pin 2 allows you to set the switching frequency of the TPS53219ARGTR. A resistor can be connected to this pin to adjust the frequency.

By meticulously connecting each of these pins, you're positioning the TPS53219ARGTR for efficient performance in your circuit design. Always consult the official datasheet for the most up-to-date and precise information about the TPS53219ARGTR's pin configuration.
