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.
