PM8804TR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure optimal heat dissipation.
  • The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and a capacitance value between 10uF to 22uF. Consult the application note AN5323 for more detailed guidance.
  • The maximum allowed voltage drop across the internal FETs is 1.5V. Exceeding this voltage drop may lead to reduced efficiency, increased power loss, and potential damage to the device.
  • The PM8804TR has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output pin and the GND pin. The device will shut down when the current through Rs exceeds the overcurrent threshold (typically 2.5A). Consult the datasheet for more information on Rs calculation and implementation.
  • The recommended operating temperature range for the PM8804TR is -40°C to 125°C. Operating the device outside this range may affect its performance, reliability, and lifespan.
