LTM4602IV#PBF datasheet by Linear Technology

LTM4602IV#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTM4602IV?
  The maximum input voltage that can be applied to the LTM4602IV is 28V, but it's recommended to operate within 18V to ensure reliable operation.
• How do I optimize the layout for the LTM4602IV to minimize EMI?
  To minimize EMI, it's recommended to keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and direct. Additionally, use a shielded inductor and orient it to minimize radiation.
• What is the recommended input capacitor type and value for the LTM4602IV?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. X5R or X7R dielectric types are suitable for this application.
• How do I select the right inductor for the LTM4602IV?
  Choose an inductor with a high saturation current rating, low DCR, and a suitable inductance value (e.g., 1uH to 4.7uH). Consider the inductor's physical size, core material, and operating frequency when making a selection.
• What is the thermal derating curve for the LTM4602IV?
  The thermal derating curve for the LTM4602IV is not explicitly stated in the datasheet, but it can be estimated based on the package thermal resistance (RθJA) and the maximum junction temperature (TJ). Consult the manufacturer's application notes for guidance.
