The eDIP-12 package (V package) is a new 12 pin through hole package introduced by Power Integrations. This slender new through-hole (V) package is suited for low profile horizontal orientation for ultra-slim designs. The package offers excellent thermal performance as it facilitates heat transfer the PCB through source pins. Additionally an optional external heatsink may be attached to the tab which can provide more heatsinking and therefore higher power processing capability.
