PM6680A Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN2349, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The PM6680A has a programmable input voltage range. You can configure it using the I2C interface to set the input voltage range to 3.3V, 5V, or 12V. Refer to the datasheet section 7.3.1 for the I2C register settings and the application note AN2349 for more information.
  • The maximum current rating for the output pins is 50mA per pin. However, the total current consumption should not exceed 200mA to ensure reliable operation and prevent overheating. Refer to the datasheet section 6.1 for more information on output current capabilities.
  • The PM6680A has built-in OVP and UVP features. You can configure the threshold voltages using the I2C interface. Refer to the datasheet section 7.3.2 for the I2C register settings and the application note AN2349 for more information on implementing OVP and UVP.
  • The PM6680A has a thermal pad on the bottom of the package. STMicroelectronics recommends using a thermal interface material (TIM) and a heat sink to dissipate heat. Refer to the datasheet section 5.2 for thermal management guidelines and the application note AN2349 for more information.
