LM2623AMM datasheet by Texas Instruments

LM2623AMM Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2623AMM?
  The maximum input voltage that can be applied to the LM2623AMM is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the LM2623AMM is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF capacitor between the VCC and GND pins to filter out noise.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.05 ohms, but it's recommended to use a capacitor with an ESR of 0.01 ohms or less for optimal performance.
• Can I use the LM2623AMM in a high-temperature environment?
  The LM2623AMM is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to prevent overheating and ensure reliability.
• How do I calculate the output voltage of the LM2623AMM?
  The output voltage of the LM2623AMM can be calculated using the formula: Vout = (R1 / R2) * (Vref - Vfb), where R1 and R2 are the feedback resistors, Vref is the reference voltage, and Vfb is the feedback voltage.
