LM5045SQX/NOPB Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the LM5045SQX/NOPB is -40°C to 125°C.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR of 1Ω or less is recommended. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
  • The maximum input voltage that the LM5045SQX/NOPB can handle is 60V.
  • The LM5045SQX/NOPB has a built-in overcurrent protection feature that limits the output current to 2.5A. Additionally, an external current sense resistor can be used to detect overcurrent conditions and shut down the device.
  • The typical quiescent current of the LM5045SQX/NOPB is 2.5mA.
