LM2576HVS-12/NOPB datasheet by Texas Instruments

LM2576HVS-12/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2576HVS-12/NOPB?
  The maximum input voltage is 40V, but it's recommended to keep it below 35V 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 (Cout) value of 10uF to 22uF, and keep the input capacitor (Cin) value between 10uF to 100uF.
• What is the minimum input voltage required for the LM2576HVS-12/NOPB to operate?
  The minimum input voltage required is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2576HVS-12/NOPB in a high-temperature environment?
  The LM2576HVS-12/NOPB is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation.
• How do I calculate the output current capability of the LM2576HVS-12/NOPB?
  The output current capability can be calculated using the formula: Iout = (Vin - Vout) / Rsc, where Rsc is the current sense resistor value.
