BD48K31G-TL Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a thermal relief pattern and a solid ground plane is recommended. Ensure a minimum of 1mm clearance around the package for airflow.
  • Use a capacitor with an ESR of 10Ω or less, and add a 1-2Ω series resistor to dampen oscillations. Also, ensure the capacitor is rated for the output voltage and ripple current.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this may cause damage to the internal circuitry.
  • The device is rated for operation up to 105°C. However, ensure proper thermal design and derate the output current accordingly to prevent overheating.
  • Use the formula: ΔVout = (Iout * ESR) / (fsw * Cout), where Iout is the output current, ESR is the output capacitor's equivalent series resistance, fsw is the switching frequency, and Cout is the output capacitance.
