DESCRIPTION
6W Royer oscillator transformer, turns ratio 67:1,
secondary (pins 10 and 6) : primary (pins 1 and 3),
primary magnetizing inductance (L
P
) of 44μH ±20%
Note:
Component values depend on lamp characteristics. See Table 3 to select values.
Note:
f
ROY
= Royer oscillator damped resonant oscillation frequency. T1 primary magnetizing inductance (L
P
) = 44μH ±20%.
VCT = average voltage from the T1 center tap to the emitters of Q1 and Q2 (ignoring Q1, Q2 V
CE,SAT
).
C1 = 0.1μF ± 20%; C2 = ±10% tolerance; R1 = ±1% tolerance.
