LM2676S-12 datasheet by Texas Instruments

LM2676S-12 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2676S-12?
  The maximum input voltage that can be applied to the LM2676S-12 is 15V, but it's recommended to keep it below 14V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable output voltage, 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-12 to operate?
  The minimum input voltage required for the LM2676S-12 to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2676S-12 in a high-temperature environment?
  The LM2676S-12 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 reliable operation.
• How do I calculate the output current capability of the LM2676S-12?
  The output current capability of the LM2676S-12 can be calculated using the formula: Iout = (Vin - Vout) / Rds(on), where Rds(on) is the on-resistance of the internal switch.
