LM5009MM datasheet by Texas Instruments

LM5009MM Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM5009MM can handle?
  The LM5009MM can handle input voltages up to 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
• How do I ensure the LM5009MM is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins.
• What is the minimum input voltage required for the LM5009MM to operate?
  The minimum input voltage required for the LM5009MM to operate is 6.5V, but it's recommended to keep it above 7V for optimal performance.
• Can I use the LM5009MM in a high-temperature environment?
  The LM5009MM is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliability and prevent overheating.
• How do I calculate the output voltage of the LM5009MM?
  The output voltage of the LM5009MM can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors in the feedback network, VIN is the input voltage, and VREF is the internal reference voltage (1.21V).
