LTC3621IMS8E#TRPBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC3621 involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. A 4-layer PCB with a dedicated power plane is recommended.
  • To ensure the LTC3621 operates within its SOA, monitor the input voltage, output current, and junction temperature. Ensure the input voltage is within the recommended range, the output current is within the maximum rating, and the junction temperature is below the maximum rating of 125°C.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 1.5 times the maximum input voltage.
  • Choose an output capacitor with a low ESR and a value of 10uF to 47uF. The capacitor should be placed close to the VOUT pin and have a voltage rating of at least 1.5 times the output voltage. A ceramic or polymer capacitor is recommended.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. The EN pin can be connected to a logic signal or a switch to control the regulator's operation.
