LT1945EMS#PBF Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is less than 1 ohm. Additionally, use a low-ESR input capacitor and keep the input and output capacitors close to the IC.
  • The maximum input voltage is 28V, but it's recommended to operate the device within the specified input voltage range of 3.5V to 24V for optimal performance and reliability.
  • The LT1945EMS#PBF is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the output current at high temperatures.
  • The output voltage ripple and noise can be calculated using the formulae provided in the datasheet. Additionally, consider using a low-pass filter or a pi-filter to reduce the output voltage ripple and noise.
