Planar Magnetics
For Texas Instruments
UCC3580
This planar transformer and planar inductor pair is designed 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.
