... RF Oscillator timing resistor pin. A buffer set alternatively to V connected between pin 2 and 3. Alternatively, the signal on pin 2 can be used also to drive another IC (i.e. another L6569 to drive a full H-bridge Oscillator timing capacitor pin. A capacitor connected between this pin and GND fixes (together with R frequency Alternatively an external logic signal can be applied to the pin to drive the IC ...

... Bootstrap Function The L6569 has an internal Bootstrap structure that enables the user to avoid the external diode needed, in sim- ilar devices, to perform the charge of the bootstrap capacitor that, in turns, provide an appropriate driving to the Upper External Mosfet. The operation is achieved with an unique structure (patented) that uses a High Voltage Lateral DMOS driven by an internal charge pump (see Block Diagram) and synchronized, with a 50 nsec delay, with the Low Side Gate driver (LVG pin), actually working as a synchronous rectifier ...

... L6569 L6569A DEMO BOARD To allow an easy evaluation of the device, a P.C. board dedicated to lamp ballast application has been de- signed. Fig.11 shows the electrical schematic of a typical ballast application, while the PC and component layout is giv Fig12. This application has been designed to work with both the 110+/-20%V and the 220 +/- 20%V mains by means of a voltage doubler configuration at the bulk capacitor ...
