TPS3809J25DBVTG4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the device placed close to the power source, and the input capacitor (CIN) placed as close as possible to the VIN pin. The output capacitor (COUT) should be placed close to the VOUT pin. A solid ground plane and short traces are also recommended to minimize noise and improve stability.
  • The input capacitor (CIN) should have a low ESR and be rated for the input voltage. A 10uF to 22uF ceramic capacitor is recommended. The output capacitor (COUT) should have a low ESR and be rated for the output voltage. A 10uF to 47uF ceramic capacitor is recommended. The capacitor values and types may vary depending on the specific application and requirements.
  • The TPS3809J25DBVTG4 has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum input voltage can damage the device.
  • The output voltage of the TPS3809J25DBVTG4 is adjustable using an external resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • The power dissipation of the TPS3809J25DBVTG4 depends on the input voltage, output voltage, and output current. The maximum power dissipation is approximately 1.5W. However, the device can operate at higher temperatures with derating. It's essential to calculate the power dissipation and ensure the device is operated within the recommended temperature range.
