PIExpert will not give me a full selection of YN devices.

The HX series datasheet shows TOP254 to TOP261 devices available in the YN (TO-220) package, but the software only shows Top254 to TOP258 devices to choose from. Why?
Also, why is the GX series moved to the archived datasheet area? Are they not recommended for new designs?
Hi
TOP259Y-TOP261Y are only available if you select 66kHz switching frequency.
As for your TopSwitch-GX, we tend to recommend the latest generations only. These guidelines are mainly for new users in order to help them choose. The latest generations tend to offer tighter tolerances, and better performance.
