SG3525AP Frequently Asked Questions (FAQ)

  • The maximum voltage rating for the SG3525AP is 40V, but 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 SG3525AP operates within a recommended frequency range of 100Hz to 500kHz. Ensure that the oscillator frequency is set within this range by selecting the correct values for RT and CT, and adjusting them as needed based on the specific application requirements.

  • Key considerations for layout and PCB design include keeping the power supply and output stages separate, using a solid ground plane, and minimizing the length of the feedback loop to reduce noise and EMI.
