LP3972SQ-E514/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern on the top layer to improve thermal performance. A minimum of 2 oz copper thickness is recommended for the top layer.
  • The LP3972SQ-E514/NOPB has a power-on reset (POR) circuit that ensures the device is properly powered up and configured during startup. The POR circuit monitors the input voltage and ensures that the device is reset until the input voltage reaches the minimum operating voltage. Additionally, the device has a built-in soft-start circuit that gradually ramps up the output voltage to prevent inrush currents.
  • The LP3972SQ-E514/NOPB has a maximum output current capability of 2A. However, the actual output current capability may be limited by the thermal performance of the device and the PCB layout. It is recommended to derate the output current based on the ambient temperature and the thermal performance of the device.
  • The LP3972SQ-E514/NOPB has built-in overvoltage protection (OVP) and undervoltage protection (UVP) circuits that protect the device from input voltage faults. The OVP circuit limits the input voltage to a maximum of 18V, while the UVP circuit ensures that the device is disabled when the input voltage falls below 2.5V. Additionally, it is recommended to add external overvoltage and undervoltage protection circuits to ensure the device is protected from input voltage faults.
  • Texas Instruments recommends using a high-quality, low-ESR ceramic capacitor with a value of 10uF to 22uF as the input capacitor. The input capacitor should be placed as close as possible to the device's input pins to minimize noise and ensure optimal performance.
