BD7931F-E2 Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC to improve heat dissipation. A 2-layer or 4-layer PCB with a thermal relief pattern is also recommended to reduce thermal resistance.
  • To ensure stable output voltage regulation, it is recommended to use a 10uF or larger output capacitor with a low ESR (Equivalent Series Resistance) and to minimize the distance between the output capacitor and the IC.
  • The maximum input voltage that can be applied to the VIN pin is 18V, but it is recommended to keep it below 15V for optimal performance and reliability.
  • The BD7931F-E2 is rated for operation up to 105°C, but it is recommended to derate the output current and input voltage to ensure reliable operation in high-temperature environments.
  • The BD7931F-E2 has built-in overcurrent protection (OCP) and thermal shutdown (TSD) features. However, it is recommended to add external protection components, such as fuses or PTC thermistors, to ensure additional protection against overcurrent and overheating.
