BD9251FV-E2 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short and wide traces for the power lines.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the ESR (Equivalent Series Resistance) of the capacitor is less than 1 ohm. Also, add a 10nF capacitor between the FB pin and GND for noise filtering.
  • The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = 0.8V x (R1/R2 + 1), where R1 and R2 are the resistors connected to the FB pin.
  • The thermal resistance of the QFN24 package is 35°C/W (junction-to-ambient) and 10°C/W (junction-to-case).
