PFC Boost Inductor ForONSemiconductor
NCP1606 PFC Controller
• Designed to operate in 100 Watt applications.
• Referenced as L_BOOST in application note AND8282/D.
• Auxiliary winding provides zero current detection (ZCD) infor-
mation and can also supply power to the NCP1606.
• 1000 Vrms winding to winding and winding to core isolation

1. Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/
HP 4284A impedance analyzer or equivalent.
2. DCR measured on Cambridge Technology micro-ohmmeter.
3. Leakage inductance is for the primary and measured with pins 4 and 8
shorted.
4. Current that causes a 40ºC temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
