PFC Choke ForSTMicroelectronics
L6562 PFC Controller
This power factor correction choke is designed specifi-
cally for the STMicroelectronics L6562 PFC controller. It
is intended for use in IEC61000-3-2 compliant switch
mode power supplies used in televisions, desktop PCs
and high-end ac-dc adapters/chargers.
The EB0057-DL is the RoHS-compliant version of the
EB0057-C. It is electrically identical and fits the recom-
mended PC board layout.
Coilcraft can design custom transformers with voltage,
inductance and DCR values to meet your specific re-
quirements. Contact Coilcraft for more information or for
free evaluation samples.

1. Inductance measured at 50 kHz, 0.1 Vrms, 0 Adc.
2. Isolation measured from pins 1 and 2 to pins 13 and 14 with voltage applied for 2 seconds.
3. DC current at which the inductance drops 10% (typ) from its value without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
