TPS3820-50DBVR Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the TPS3820-50DBVR involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note 'TPS3820 Layout and Placement Guidelines' for more information.
  • The input capacitor should have a low ESR and be rated for the input voltage. A 10uF to 22uF ceramic capacitor is recommended. The output capacitor should be a low-ESR ceramic capacitor with a value of 10uF to 22uF. The capacitor selection should be based on the output voltage, output current, and ripple requirements.
  • The TPS3820-50DBVR can handle an input voltage up to 6.5V. However, the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the maximum input voltage can damage the device.
  • The output voltage of the TPS3820-50DBVR can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 0.5V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • The thermal shutdown temperature of the TPS3820-50DBVR is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 130°C.
