LP3910SQX-AP/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device to improve thermal performance. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • To ensure reliable start-up, Texas Instruments recommends a soft-start circuit to limit the inrush current and a bulk capacitor of at least 10uF to filter the input voltage. Additionally, a minimum input voltage of 2.5V is recommended for reliable start-up.
  • The LP3910SQX-AP/NOPB can deliver up to 1.5A of output current, but this is dependent on the input voltage, output voltage, and thermal conditions. It's recommended to consult the datasheet and application notes for specific guidance on output current capability.
  • The output voltage of the LP3910SQX-AP/NOPB can be adjusted by using a resistive divider network between the output and the feedback pin. The recommended resistive divider ratio is 1:1 to 1:10, and the output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2).
  • The LP3910SQX-AP/NOPB has a maximum junction temperature of 150°C. To ensure reliable operation, the device should be operated within a temperature range of -40°C to 125°C. Thermal considerations such as thermal resistance, power dissipation, and heat sinking should be taken into account during design and layout.
