For National Semiconductor

Planar Magnetics _{LM5025 and LM5034}

This planar transformer and planar inductor pair is de-

signedspecificallyfortheNationalSemiconductorLM5110

Gate Driver and LM5025 Active Clamp Voltage Mode

PWMController. ThesepartsarealsospecifiedbyNSCfor

use with their LM5034 Dual Interleaved Controller.

The B0357-B transformer is engineered for use in high

current telecom power supply applications that require

high efficiency in a low-profile package.

The main winding of the B0358-CC inductor serves as an

output choke, while the auxiliary winding controls input

current to the PWM.

1. When ordering, please specify packaging code:

B0357-BLD

3. Leakage inductance measured between pins 1 and 2 at 100 kHz,

0.1 Vrms, 0 Adc with secondary pins shorted.

4. Ambient temperature range:

5. Storage temperature range: Component:

Packaging:

–

40°C to +85°C

40°C to +80°C

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic

–

tape (200 parts per full reel).

–

B = Less than full reel. In tape, but not machine ready. To

have a leader and trailer added ($25 charge), use

code letter D instead.

6. Resistance to soldering heat: Three reflows at >217°C for 90 seconds

(+260°C 5°C for 20 – 40 seconds), allowing parts to cool to room

temperature between.

7. Electrical specifications at 25°C.

2. Inductance measured on an Agilent/HP 4284 between pins 1 and 2 at

250 kHz, 0.1 Vrms, 0 Adc.
