LMZ21700SILT Frequently Asked Questions (FAQs)

  • A good PCB layout for the LMZ21700SILT involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. TI provides a recommended PCB layout in the datasheet and application notes.
  • To ensure the LMZ21700SILT operates within its SOA, monitor the input voltage, output current, and junction temperature. Ensure the device is not subjected to excessive voltage, current, or temperature stress. Refer to the datasheet for the recommended operating conditions and thermal management guidelines.
  • 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 6.3V.
  • Choose an output capacitor with a low ESR and a value of 10uF to 22uF. The capacitor should be placed close to the VOUT pin and have a voltage rating of at least 2.5V. Consider the output capacitor's ripple current rating and ensure it can handle the maximum output current.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is high (above 1.4V), the device is enabled, and when it's low (below 0.4V), the device is disabled. Connect the EN pin to a logic signal or a voltage source to control the device's operation.
