Output Power Table
Notes:
1. Maximum output power is limited by device internal current limit. 2. See Applications Considerations section of the DPA-Switch data sheet 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 packages. 4. Packages: P: DIP-8, G: SMD-8, R: TO-263-7C. For lead-free
package options, see Part Ordering section of the DPA-Switch data sheet. 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.
