Flyback Transformer Flyback Green Mode Controller
Core material Ferrite
Terminations RoHS tin-silver over tin over nickel over phos
bronze. Other terminations available at additional cost.
Weight 89.2 g
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
Ambient temperature –40°C to +85°C
operate in discontinous conduction mode at frequen-
cies up to 140 kHz.
Storage temperature Component: –40°C to +85°C.
Packaging: –40°C to +80°C
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
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.
