LM2576S-ADJ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576S-ADJ is 40V. Exceeding this voltage can cause damage to the device.
  • The output voltage of the LM2576S-ADJ can be set by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
  • The minimum input voltage required for the LM2576S-ADJ to operate is 3V. However, the device can operate down to 2.5V with reduced performance.
  • The LM2576S-ADJ is rated for operation up to 125°C. However, the device's performance may degrade at high temperatures, and the output voltage may drop. It's recommended to derate the output current at high temperatures.
  • To ensure the stability of the LM2576S-ADJ output voltage, it's recommended to use a minimum output capacitance of 10uF and to keep the output voltage sensing point close to the load.
