Planar Transformers Document 305 Document 305 Revised 09/30/05 Less than 10 mm high, Coilcraft’s planar transformers are ideal for use in high-current telecom power supply appli- cations that require high efficiency in a low-profile package. These transformers are designed specifically to perform with the National Semiconductor LM5030 Push-Pull Cur- rent Mode PWM Controller. They provide three different output ratings to suit a variety of applications All offer 1500 Vrms primary to secondary isolation. Coilcraft’s A9785-B, A0153-A and B0414-A are output chokes and include an extra winding for auxiliary voltage supply. Our MSS6132-103 functions as the input filter choke in the same circuit.

When ordering, please specify packaging code: B0310-AL D Packaging: D =1 3″ machine ready reel. EIA-481 embossed plastic tape (250 parts 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.

The 33 Watt design specifies our A9785-B, the 35 Watt design uses the A0153-A and the 60 Watt design uses the B0414-A. They are the output chokes for Coilcraft’s planar trans- formers (A9784-B, A0152-A and B0310-A). The auxil- iary winding controls the input current to the PWM. All inductors offer 1500 Vrms main to auxiliary isolation. The National Semiconductor design also specifies Coilcraft’s MSS6132-103 power inductor for the input choke.
