LTC3528BEDDB-2#TRMPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating above the peak current of the converter, and a DC resistance that minimizes power loss.
  • For optimal performance, keep the power components (inductor, capacitors, and IC) close together, and use a solid ground plane to reduce noise and EMI. Keep the feedback network (FB, COMP, and VOUT) away from the power components and use a separate analog ground plane.
  • The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula: VOUT = 0.8V x (1 + R2/R1) to calculate the desired output voltage.
  • The EN (enable) pin is used to turn the converter on and off. Connect EN to VIN to enable the converter, or connect it to GND to disable it. You can also use an external signal to control the EN pin for dynamic power management.
