GENERAL DESCRIPTION
The ADP1071-1EVALZ allows users to evaluate the
ADP1071-1
in flyback topology.
The evaluation board is set up to act as an isolated power supply
solution that incorporates three output voltages (+5.5 V, +24 V,
and −15 V) at a total rated power of 15 W. The evaluation board
also provides 5 kV isolation in compact form factor, making it
suitable for industrial applications, which usually have a variety
of voltage rails.
