For Texas Instruments
Planar Magnetics UCC3580
This planar transformer and planar inductor pair is de-
signed specifically for the Texas Instruments UCC3580
family of PWM controllers.
The B0392-AL transformer is engineered for use in single
switch, forward topologies operating at 300 kHz. It is ideal
for use in high-current telecom power supply applications
that require high efficiency in a low-profile package.
The main winding of the B0434-AL inductor serves as an
output choke, while the auxiliary winding controls input
current to the PWM.

1. When ordering, please specify packaging code:
B0392-ALD
2. Inductance measured on an Agilent/HP 4284 between pins 1 and 2 at
250 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 1 and 2 at 100 kHz, 0.1Vrms,
0 Adc with secondary pins shorted.
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 parts per full reel).
4. Electrical specifications at 25°C.
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
