SG3524DR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the SG3524DR is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure stability, make sure to decouple the power supply pins (VCC and GND) with a 10uF capacitor, and use a 1kΩ resistor in series with the feedback pin (FB) to prevent oscillations.
  • The soft-start pin (SS) is used to gradually increase the output voltage during startup, reducing inrush currents. Connect a capacitor (typically 10nF to 100nF) from SS to GND to set the soft-start time.
  • The output voltage (Vout) can be calculated using the formula: Vout = (1 + R2/R1) * (Vref * (R3/R4)), where R1, R2, R3, and R4 are the resistors in the feedback network, and Vref is the internal reference voltage (5V).
  • The maximum output current that the SG3524DR can deliver is 500mA. Exceeding this current can cause overheating and damage to the device.
