TPSM84212EAB Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias under the device is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Ensure that the input voltage rises monotonically during start-up, and falls monotonically during shutdown. Also, add a soft-start capacitor to limit the inrush current and prevent voltage overshoot.
  • The maximum allowed output capacitance is 100uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • Implement overcurrent protection using a sense resistor and a comparator. Also, monitor the device temperature using a thermistor or a thermal sensor, and shut down the device if it exceeds the maximum allowed temperature.
  • Use a pi-filter configuration with a series inductor, a shunt capacitor, and a common-mode choke to reduce EMI emissions and improve conducted emissions.
