LM2575HVT-12/NOPB datasheet by Texas Instruments

LM2575HVT-12/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2575HVT-12/NOPB?
  The maximum input voltage is 60V, but it's recommended to keep it below 50V 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 and type, and keep the input voltage within the specified range. Also, ensure the PCB layout is well-designed to minimize noise and EMI.
• What is the maximum output current I can draw from the LM2575HVT-12/NOPB?
  The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I protect the LM2575HVT-12/NOPB from overheating?
  To prevent overheating, ensure good airflow around the device, use a heat sink if necessary, and keep the input voltage and output current within the recommended ranges.
• Can I use the LM2575HVT-12/NOPB in a high-temperature environment?
  The LM2575HVT-12/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating.
