CFL power IC

[1]

The start-up supply current is speciﬁed in a temperature (Tvj) range of 0 °C to 125 °C. For Tvj <0 °C and Tvj > 125 °C

the start-up supply current is < 350

µA.

[2]

The clamp margin is deﬁned as the voltage difference between turn-on of the clamp and start of oscillation. The clamp is in the off-state

at start of oscillation.

[3]

Data sampling of Vth(capm) is performed at the end of conduction of T2.

[4]

Data sampling of Vth(capm) is performed at the start of conduction of T2.

[5]

Within the allowed range of RIREF, deﬁned as 30 kΩ +10%.

[6]

The input current at pin RHV may increase to 1.6 mA during voltage transient on pin VDC. Only for pin RHV currents beyond

approximately 550 mA the oscillator frequency is proportional to the pin RHV current.

[7]

The symmetry is best calculated using fff(ratio) where fff(ratio) = T1 total time divided by the T2 total time with the T1 total time the time

between turn-off of G2 and turn-off of G1, and the T2 total time the time between turn-off of G1 and turn-off of G2.
