BD2045AFJ-E2 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 to ensure stable operation. Additionally, a 1μF or larger ceramic capacitor in parallel with the output capacitor can help improve stability.
  • The maximum allowed voltage on the EN pin is 6V, which is the same as the maximum input voltage of the device. Exceeding this voltage may damage the internal circuitry.
  • The BD2045AFJ-E2 is rated for operation up to 125°C, but the maximum junction temperature (Tj) should not exceed 150°C. Ensure proper thermal design and heat dissipation to prevent overheating.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
