LM2676S-3.3 datasheet by Texas Instruments

LM2676S-3.3 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2676S-3.3?
  The maximum input voltage that can be applied to the LM2676S-3.3 is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure the output voltage is stable and regulated, make sure to use the recommended output capacitor (22uF) and input capacitor (10uF) values, and keep the input voltage within the recommended range.
• What is the minimum input voltage required for the LM2676S-3.3 to operate?
  The minimum input voltage required for the LM2676S-3.3 to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2676S-3.3 in a high-temperature environment?
  The LM2676S-3.3 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation. Make sure to provide adequate heat sinking and thermal management.
• How do I calculate the output current capability of the LM2676S-3.3?
  The output current capability of the LM2676S-3.3 is dependent on the input voltage and the output voltage. Use the formula: Iout = (Vin - Vout) / Rds(on) to calculate the maximum output current. Rds(on) is the on-resistance of the internal switch, which is typically around 0.5 ohms.
