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.
