LT3478IFE-1#PBF datasheet by Linear Technology

LT3478IFE-1#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT3478IFE-1#PBF?
  The maximum input voltage that can be applied to the LT3478IFE-1#PBF is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• Can I use the LT3478IFE-1#PBF in a high-temperature environment?
  The LT3478IFE-1#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability and prevent thermal shutdown.
• How do I ensure the stability of the output voltage in the LT3478IFE-1#PBF?
  To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF, and to follow the recommended PCB layout and component placement guidelines in the datasheet.
• Can I use the LT3478IFE-1#PBF in a low-input-voltage application?
  The LT3478IFE-1#PBF has a minimum input voltage of 2.5V, but it's recommended to keep the input voltage above 3V for optimal performance and to ensure that the internal voltage regulator can operate correctly.
• How do I calculate the power dissipation of the LT3478IFE-1#PBF?
  The power dissipation of the LT3478IFE-1#PBF can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
