SG3524N Frequently Asked Questions (FAQs)

  • The maximum voltage rating for the SG3524N is 40V. However, it's recommended to operate it within 30V to ensure reliable operation.
  • The values of RT and CT depend on the desired oscillator frequency. A good starting point is to use the values recommended in the datasheet (RT = 2.2kΩ, CT = 3.3nF) and then adjust them based on the specific application requirements.
  • The soft-start pin (SS) is used to gradually increase the output voltage during startup, reducing inrush currents and electromagnetic interference (EMI). Connect a capacitor (typically 10nF to 100nF) from the SS pin to ground and a resistor (typically 1kΩ to 10kΩ) from the SS pin to the output voltage.
  • The operating mode depends on the inductor value, output current, and switching frequency. For CCM, use a larger inductor value and ensure the inductor current ripple is less than 20% of the output current. For DCM, use a smaller inductor value and ensure the inductor current ripple is greater than 20% of the output current.
  • The maximum output current capability of the SG3524N is 1A per channel. However, the actual output current depends on the application, PCB layout, and thermal considerations.
