The C1539-AL was developed specifically for the Na-

tional Semiconductor LM5032 dual interleaved current

mode PWM controller. This planar transformer can be

used in a dual forward converter or in both interleaved

power stages of a high-current converter in applications

up to 100 Watts.

Its low leakage inductance and excellent dc resistance

provide very high efficiency. Primary to secondary isola-

tion is 1500 Vdc.
