Flyback Transformer ForTIUCC28600 Flyback Green Mode Controller
The FA2443-AL was developed specifically for Texas Instruments UCC28600 Quasi-Resonant Flyback Green Mode Controller and is specified in SLUU256A for the
evaluation module. This transformers is designed to operate in discontinous conduction mode at frequencies up to 140 kHz.

1. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc. 2. Peak primary current drawn at minimum input voltage. 3. Leakage inductance is for the primary and is measured at 100 kHz,
0.1 Vrms with all other windings shorte.
