Simple Connection www.micropowerdirect.com

The diagram at left illustrates a typical connection of the IG480 series.
Capacitors C1, C2 and C3 are fi ltering components and are required to meet the
datasheet specifi cations. For many applications, this setup will be suffi cient.
The recommended component values are given in the table below.

VIN C1 (µF) C2 (µF) C3 (µF)
12 VDC 100 100 100
24 VDC 100 100 100
