Detailed Design Procedure

LMZ10504 is fully supported by WEBENCH and offers the following: component selection, performance, electrical, and thermal simulations as well as the Build-It board, for a reduced design time. On the other hand, all external components can be calculated by following the design procedure below.

  1. Determine the input voltage and output voltage. Also, make note of the ripple voltage and voltage transient requirements.
  2. Determine the necessary input and output capacitance.
  3. Calculate the feedback resistor divider.
  4. Select the optimized compensation component values.
  5. Estimate the power dissipation and board thermal requirements.
  6. Follow the PCB design guideline.
  7. Learn about the LMZ10504 features such as enable, input UVLO, soft start, tracking, prebiased start-up, current limit, and thermal shutdown.
