LTC1174HVCS8-5 datasheet by Linear Technology

LTC1174HVCS8-5 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1174HVCS8-5?
  The maximum input voltage that can be applied to the LTC1174HVCS8-5 is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the LTC1174HVCS8-5 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF capacitor between the VCC and GND pins to filter out noise.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.05 ohms, but it's recommended to use a capacitor with an ESR of 0.01 ohms or less for optimal performance.
• Can I use the LTC1174HVCS8-5 in a high-temperature environment?
  The LTC1174HVCS8-5 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage ripple of the LTC1174HVCS8-5?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESR) / (fsw * Cout), where Iout is the output current, ESR is the output capacitor's ESR, fsw is the switching frequency, and Cout is the output capacitance.
