Planar Transformer For National Semiconductor
LM5032 PWM Controller
• Developed for the NSC LM5032 dual interleaved current mode
PWM controller for applications up to 100 Watts.
• Can be used in a dual forward converter or in both interleaved
power stages of a high-current converter.
• Low leakage inductance, excellent DCR
• Interwinding isolation: 1500 Vdc.

1. When ordering, please specify a packaging code:
Packaging:
C1539-ALD
D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
2. Inductance measured on an Agilent/HP 4284 between pins 2 and 4 at 250
kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 2 and 4 at 100 kHz, 0.1 Vrms,
0 Adc with pins7 and 9 shorted.
4. Storage and ambient operating temperature range: –40°C to +85°C.
5. Electrical specifications at 25°C.
