BD535 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the BD535?
  The BD535 can operate from -40°C to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure the BD535 is properly biased for optimal performance?
  To ensure proper biasing, the input voltage (VIN) should be between 4.5V and 18V, and the output voltage (VOUT) should be set to the desired value using the feedback resistors (R1 and R2).
• What is the recommended input capacitor value and type for the BD535?
  A 10uF to 22uF ceramic or electrolytic capacitor with a low ESR (Equivalent Series Resistance) is recommended for the input capacitor (CIN) to ensure stability and reduce noise.
• How do I calculate the output voltage (VOUT) of the BD535?
  The output voltage (VOUT) can be calculated using the formula: VOUT = (1 + R2/R1) * VREF, where VREF is the internal reference voltage (typically 2.5V) and R1 and R2 are the feedback resistors.
• What is the maximum output current capability of the BD535?
  The BD535 can deliver up to 3A of output current, but the maximum current should be derated based on the ambient temperature and the package thermal resistance (RθJA).
