LT1910ES8 datasheet by Linear Technology

LT1910ES8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1910ES8?
  The maximum input voltage that can be applied to the LT1910ES8 is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the LT1910ES8 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a 10uF ceramic capacitor at the output, and a 1uF ceramic capacitor at the input. Also, keep the input and output capacitors close to the device.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR may cause instability or oscillation.
• Can I use the LT1910ES8 in a high-temperature environment?
  The LT1910ES8 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage ripple of the LT1910ES8?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESR) / (f x Cout), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and Cout is the output capacitance.
