LT1633CS datasheet by Linear Technology

LT1633CS Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1633CS?
  The maximum input voltage that can be applied to the LT1633CS is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the LT1633CS 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.
• Can I use the LT1633CS in a high-temperature environment?
  The LT1633CS is rated for operation up to 125°C, but its 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 LT1633CS?
  The output voltage ripple 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.
• Can I use the LT1633CS in a battery-powered device?
  Yes, the LT1633CS is suitable for battery-powered devices due to its low quiescent current (IQ) of 2.5mA. However, make sure to consider the battery life and overall system power consumption when designing the power supply.
