for TI UCC25230
Switching Converter
Flyback/ Buck Transformer
The MA5401-AE was developed for use with the Texas In-
struments UCC25230 Switching Converter (12 – 100 V input,
0.20 A output).
It is designed to meet UL60950 Functional Isolation for
working voltage up to 210 V peak.
With 1000 Vrms (1500 Vdc) hipot and a small package size,
this transformer is ideal for use in high density isolated circuit
applications.
It provides tight coupling (k>0.99), high inductance and
excellent current handling in a rugged, low cost part.
