BD4842FVE-TR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • ROHM recommends using an output capacitor with an ESR of 10Ω or less. Additionally, a 1μF ceramic capacitor in parallel with the main output capacitor can help improve stability.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
  • The BD4842FVE-TR is rated for operation up to 125°C. However, derating the output current and ensuring proper thermal management are necessary to ensure reliable operation at high temperatures.
  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Iq is the quiescent current. ROHM provides a power dissipation calculator on their website to simplify this calculation.
