LT1079SW datasheet by Linear Technology

LT1079SW Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1079SW can handle?
  The LT1079SW can handle input voltages up to 60V, but it's recommended to keep the input voltage below 50V for optimal performance and reliability.
• How do I ensure stability in the LT1079SW switching regulator?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF ceramic capacitor between the Vc pin and ground to filter out noise.
• Can I use the LT1079SW in a high-temperature environment?
  The LT1079SW is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliability and prevent thermal shutdown.
• How do I calculate the output voltage ripple of the LT1079SW?
  The output voltage ripple can be estimated using the formula: ΔVout = (Iout * Rl) / (fsw * Cout), where Iout is the output current, Rl is the inductor resistance, fsw is the switching frequency, and Cout is the output capacitor value.
• What is the recommended inductor value and type for the LT1079SW?
  The recommended inductor value is between 10uH to 22uH, and a low-loss, high-current inductor such as a ferrite or powdered iron core inductor is recommended. The datasheet provides a list of recommended inductors.
