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 frequen-
cies up to 140 kHz.
Coilcraft can also custom engineer a transformer to
meet your specific requirements.

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 shorted.
4. Turns ratio for the secondary is with the windings connected in
parallel
5. Isolation is from the primary to all other windings.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
