LTC3335IUDC#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal components.
  • To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive analog nodes.
  • The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (DC Resistance) is recommended. The inductor type should be a high-current, low-loss inductor with a high saturation current rating.
  • The output voltage can be adjusted by changing the resistor divider ratio of the FB (Feedback) pin. A higher resistor value will increase the output voltage, while a lower value will decrease it. However, it's recommended to use the recommended resistor values in the datasheet to ensure optimal performance.
  • The maximum output current that the LTC3335IUDC#PBF can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
