LM2662MX datasheet by Texas Instruments

LM2662MX Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2662MX can handle?
  The LM2662MX can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use the recommended output capacitor value and type, and keep the output voltage within the specified range. Also, ensure that the input voltage is within the recommended range and the input capacitor is properly sized.
• What is the minimum input capacitance required for the LM2662MX?
  The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability and optimal performance.
• Can I use the LM2662MX in a high-temperature environment?
  The LM2662MX is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent overheating.
• How do I calculate the output voltage of the LM2662MX?
  The output voltage of the LM2662MX can be calculated using the formula: Vout = (R1 / R2) * (1.25V), where R1 and R2 are the resistors used in the feedback network.
