PlanarTransformers LM5030 Controller IC
Lessthan10 mmhigh,Coilcraft’splanartransformersare
ideal for use in high-current telecom power supply appli-
cationsthatrequirehighefficiencyinalow-profilepackage.
Thesetransformersare designedspecificallytoperform
withtheNationalSemiconductorLM5030Push-PullCur-
rent Mode PWM Controller. They provide three different
output ratings to suit a variety of applications.
Coilcraft’s A9785-B, A0153-A and B0414-A are output
chokesandincludeanextrawindingforauxiliaryvoltage
supply. Our MSS6132-103 functions as the input filter
choke in the same circuit. Refer to separate data sheets
for additional information on these parts.

Output Choke Inductors LM5030 Controller IC
These low-profile inductors are designed specifically for
the National Semiconductor LM5030 Push-Pull Current
ModePWMControllers.The33 Wattdesignspecifiesour
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-AandB0310-A).Theauxiliary
winding controls the input current to the PWM.
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.

Input Choke Inductor LM5030 Controller IC
The MSS6132 power inductor is specified by National
SemiconductorforitsLM5030controllerIC. Itactsasthe
input choke for Coilcraft’s A9784-B planar transformer
(see separate data sheet).
This magnetically shielded, low-profile power inductor is
designed for high-density mounting and is available on
tape and reel for auto-insertion. Its industry-standard
shape and flat top design ensures reliable pick and
place handling.
