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 All offer

1500 Vrms primary to secondary isolation.

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.

For National Semiconductor

Output Choke Inductors LM5030 Controller IC

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.
