STEVAL-ISA013V1: 24W, 12V @ 1A, 5V @ 2.4A, 85 ~ 265VAC

Summary

This board is an off-line wide range dual output general-purpose power supply capable of delivering up to 24W through two outputs, +5V and +12V. The board is configured for secondary regulation with optocoupler feedback.

Other output voltages can easily be achieved by changing the transformer and a few components on the board, as shown in the application note.
