LM9044VX/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
  • To ensure stability, make sure to follow the recommended component values and layout guidelines in the datasheet. Additionally, ensure that the input and output capacitors meet the recommended specifications, and that the feedback network is properly compensated. If oscillations occur, try adding a small capacitor (e.g. 10nF) between the VOUT and GND pins.
  • The maximum input voltage rating for the LM9044VX/NOPB is 15V, but it's recommended to operate the device within the specified input voltage range (7V to 14V) for optimal performance and reliability.
  • The LM9044VX/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation. Consult the datasheet for thermal derating guidelines.
  • The output voltage of the LM9044VX/NOPB is determined by the resistor divider network (R1 and R2) connected between the VOUT and GND pins. Use the formula: VOUT = 1.25V x (1 + R2/R1) to calculate the output voltage.
