Document 305 Planar Transformers For National Semiconductor LM5030 Controller IC Less than 10 mm high, Coilcraft’s planar transformers are ideal for use in high-current telecom power supply applications that require high efficiency in a low-profile package. These transformers are designed specifically to perform with the National Semiconductor LM5030 Push-Pull Current 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.

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 transformers (A9784-B, A0152-A and B0310-A). The auxiliary 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.
