These low-profile inductors are designed specifically for
the National Semiconductor LM5030 Push-Pull Current
Mode PWM Controllers. 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. Refer to separate data sheets for additional
information on these Coilcraft parts.
