For a 48V to 5V buck converter circuit using regulators like the L7805CV and L7812CV, typical values for the input and output capacitors can be derived from the datasheets and general guidelines.
Here are common values for these components:
  1. C1 (Input Capacitor): This capacitor is crucial for stabilizing the input voltage and smoothing out any ripples or noise. For the L7805 and L7812 voltage regulators:
    • Value: 0.33 µF to 1 µF
    • Type: Ceramic capacitors are commonly used here due to their low ESR (Equivalent Series Resistance).
  2. C2 (Output Capacitor): This capacitor helps in stabilizing the output voltage and reducing noise. For the L7805 and L7812:
    • Value: 0.1 µF to 10 µF
    • Type: Electrolytic or tantalum capacitors are typical for higher values; ceramic capacitors are also used.
  3. C3: (Additional Output Capacitor for Improved Stability): This is not always needed, but if used in parallel with C2, it can enhance stability.
    • Value: 0.1 µF
    • Type: Ceramic capacitors are ideal due to their low ESR.
Here's a connection summary:
  • C1: Connect C1C1:P2 to VinV_{in}:P1.
  • C2: Connect C2C2:P1 to U2U2:OUT.
  • C3: Connect C3C3:P2 to U1U1:OUT.
Would you like more details or alterations to these values based on specific requirements?
