Notes
1. A flyback supply voltage of >50 V up to 60 V is allowed in application. A 220 nF capacitor in series with a 22 Ω resistor
(dependent on IO and the inductance of the coil) has to be connected between pin 7 and ground. The decoupling
capacitor of VFB has to be connected between pin 8 and pin 4. This supply voltage line must have a resistance of
33 Ω (see application circuit Fig.5).
2. IO maximum determined by current protection.
3. The operating area is limited by a straight line between the points VO(sink) = 40 V; IO(sink) = 10 µA and VO(sink) = 2 V;
IO(sink) = 500 mA.
4. Up to Vp = 18 V.
