LT1076HVCT-5 datasheet by Linear Technology

LT1076HVCT-5 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1076HVCT-5?
  The maximum input voltage that can be applied to the LT1076HVCT-5 is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure stability in the LT1076HVCT-5 switching regulator?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor, input capacitor, and feedback resistors. Also, ensure that the voltage rating of the output capacitor is sufficient for the output voltage.
• What is the maximum output current that the LT1076HVCT-5 can deliver?
  The maximum output current that the LT1076HVCT-5 can deliver is 5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
• Can I use the LT1076HVCT-5 in a high-temperature environment?
  The LT1076HVCT-5 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to derate the output current and ensure proper heat sinking to prevent overheating.
• How do I reduce the noise and ripple in the LT1076HVCT-5 output?
  To reduce noise and ripple, use a suitable output capacitor with low ESR, add a noise-reducing capacitor (e.g., 10nF) between the output and ground, and ensure that the input capacitor is properly bypassed. Additionally, consider using a shielded inductor and keeping the layout compact to minimize radiated noise.
