LT1763CDE datasheet by Linear Technology

LT1763CDE Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1763CDE?
  The maximum input voltage that can be applied to the LT1763CDE is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the LT1763CDE is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a 10nF-100nF capacitor between the VIN and GND pins to filter out noise.
• What is the minimum output current that the LT1763CDE can deliver?
  The LT1763CDE can deliver a minimum output current of 1mA, but it's recommended to operate it above 10mA for optimal performance and stability.
• Can I use the LT1763CDE in a high-temperature environment?
  The LT1763CDE is rated for operation up to 125°C, but its performance and reliability may degrade above 85°C. 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 LT1763CDE?
  The output voltage ripple of the LT1763CDE can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
