LT4294HMS#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise and coupling.
  • Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) as close as possible to the VIN pin. Add additional decoupling capacitors (e.g., 100nF ceramic) near the VOUT pin. Ensure the power supply is stable and has low ripple.
  • The LT4294HMS can deliver up to 2A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions. Consult the datasheet for specific current limits and thermal derating.
  • The output voltage can be adjusted by changing the resistor ratio of R1 and R2. Use the formula: VOUT = (R2 / R1) * 0.8V + 0.8V. Ensure the resistors are 1% tolerance or better for accurate voltage setting.
  • The EN (enable) pin is an active-high input that allows the user to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled and consumes minimal quiescent current.
