LTC1735IS#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC1735IS#PBF involves separating the analog and digital grounds, using a solid ground plane, and keeping the input and output traces short and away from each other. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The LTC1735IS#PBF requires a single 3.3V or 5V power supply. It's recommended to use a low-dropout linear regulator or a switching regulator with a low noise output to power the device. The power sequencing requirement is to power up the VIN pin first, followed by the VCC pin.
  • The LTC1735IS#PBF can drive a maximum capacitive load of 1000pF. Exceeding this limit may cause instability or oscillations in the output.
  • The output voltage of the LTC1735IS#PBF can be adjusted by using an external resistor divider network connected to the FB pin. The resistor values can be calculated using the formula provided in the datasheet.
  • The thermal derating of the LTC1735IS#PBF is 1.5% per °C above 25°C. This means that the device's output current capability will decrease as the temperature increases. It's essential to ensure proper heat sinking and thermal management to maintain the device's performance.
