BD49K33G-TL 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 or larger ceramic capacitor in parallel with the main output capacitor can help stabilize the output voltage.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
  • The BD49K33G-TL is rated for operation up to 105°C. However, the device's performance and reliability may degrade at high temperatures. ROHM recommends derating the output current and voltage according to the temperature derating curve in the datasheet.
  • The power dissipation of the BD49K33G-TL can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
