Notes:

  1. Maximum output power is limited by device internal current limit.
  2. See Applications Considerations section for complete description of assumptions and for output powers with other input voltage ranges.
  3. For device dissipation of 1.5 W or below, use P or G packages. Device dissipation above 1.5 W is possible with R package.
  4. Packages: P: DIP-8, G: SMD-8, R: TO-263-7C. For lead-free package options, see Part Ordering Information.
  5. Available in R package only.
  6. Due to higher switching losses, the DPA425 may not deliver additional power compared to a smaller device.
  7. Available in P and G package only.
  8. DPA422 not recommended for new designs, use DPA423 instead.
