Planar Transformers

For National SemiconductorLM5030 Controller IC

Less than 10 mm high, Coilcraft’s planar transformers areideal 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 performwith the National Semiconductor LM5030 Push-Pull Cur-rent Mode PWM Controller. They provide three differentoutput ratings to suit a variety of applications.

Coilcraft’s A9785-B, A0153-A and B0414-A are outputchokes and include an extra winding for auxiliary voltagesupply. Our MSS6132-103 functions as the input filterchoke in the same circuit. Refer to separate data sheetsfor additional information on these parts.

Output Choke Inductors

For National Semiconductor

LM5030 Controller IC

These low-profile inductors are designed specifically forthe National Semiconductor LM5030 Push-Pull CurrentMode PWM Controllers. The 33 Watt design specifies ourA9785-B, the 35 Watt design uses the A0153-A and the60 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 auxiliarywinding controls the input current to the PWM.The National Semiconductor design also specifiesCoilcraft’s MSS6132-103 power inductor for the inputchoke. Refer to separate data sheets for additionalinformation on these Coilcraft parts.
