Document 657 -1
SMT PFC Boost Inductor For ON Semiconductor NCP1606 PFC Controller
- Designed to operate in 100 Watt applications.
- Referenced as LBOOST in application note AND8282/D.
- Auxiliary winding provides zero current detection (ZCD) information and can also supply power to the NCP1606.
- 500 Vrms winding to winding and winding to core isolation

1. When ordering, please specify packaging code:
GA2972-ALD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (50 parts per full reel).
B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2. Inductance measured at 100 k Hz, 1.1 Vrms, 0 Adc using an Agilent/ HP 4263B impedance analyzer or equivalent.
3. SRF tested on an Agilent/HP 4192A. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering...
