Document 357-1 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.
