Typical Component Values
C1 = 0.5µF, 30V.
C2 = 1.0µF ±10%, 20V (for other values of C2 , refer to
AN9667).
C3 = 0.01µF, 100V, ±20%.
C4 = 0.01µF, 100V, ±20%.
C5 = 0.01µF, 100V, ±20%.
CAC = 0.5µF, 20V.
KZ0 = 60kâ¦, (Z0 = 600â¦, K = Scaling Factor = 100).
RL1 , RL2 ; Current Limit Setting Resistors:
RL1 + RL2 > 90k⦠â offset.
ILIMIT = (0.6) (RL1 + RL2)/(200 x RL2), RL1 typically 100kâ¦.
KRF = 20kâ¦, RF = 2(RB2 + RB4), K = Scaling Factor = 100).
RB1 = RB2 = RB3 = RB4 = 50⦠(1% absolute, matching
requirements covered in a Tech Brief).
RS1 = RS2 = 1k⦠, typically.
CS1 = CS2 = 0.1µF, 200V typically, depending on VRing and
line length.
Z1 = 150V to 200V transient protector. PTC used as ring
generator ballast.
