LM5008MMX datasheet by Texas Instruments

LM5008MMX Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM5008MMX?
  The maximum operating temperature range for the LM5008MMX is -40°C to 125°C. However, it's recommended to operate within -20°C to 85°C for optimal performance.
• How do I ensure the LM5008MMX is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF to 100nF ceramic capacitor between the VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the LM5008MMX to operate?
  The minimum input voltage required for the LM5008MMX to operate is 2.7V, but it's recommended to operate with a minimum input voltage of 3V for optimal performance.
• Can I use the LM5008MMX in a high-current application?
  The LM5008MMX is designed for low-current applications up to 500mA. For high-current applications, consider using a different device, such as the LM2675 or LM5175, which can handle higher currents.
• How do I calculate the output voltage of the LM5008MMX?
  The output voltage of the LM5008MMX can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.21V).
