FS1403-3300-AL - TDK

FS1403-3300-AL Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the FS1403-3300-AL?
  TDK recommends a symmetrical layout with the component placed at the center of the PCB, and the input and output pins should be routed away from each other to minimize electromagnetic interference (EMI).
• How does the FS1403-3300-AL handle overvoltage and overcurrent conditions?
  The FS1403-3300-AL has built-in overvoltage protection (OVP) and overcurrent protection (OCP) circuits that will shut down the device in case of an overvoltage or overcurrent event, protecting the device from damage.
• What is the recommended input capacitor value and type for the FS1403-3300-AL?
  TDK recommends using a 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric, placed as close as possible to the input pins of the FS1403-3300-AL.
• Can the FS1403-3300-AL be used in high-temperature environments?
  The FS1403-3300-AL is rated for operation up to 85°C, but derating is required for temperatures above 70°C. Consult the datasheet for specific derating guidelines.
• How does the FS1403-3300-AL behave during power-up and power-down sequences?
  The FS1403-3300-AL has a soft-start feature that ramps up the output voltage during power-up, and a shutdown pin that can be used to turn off the device during power-down sequences.
