UBA22xx Power IC Family Slide 9
Boost is created with an internal counter and an external timing capacitor. In the screen shots on this slide, the light blue signal shows the external capacitor as it is charged and discharged. The green signal is the lamp discharge current. The purple line is the SW signal which is input to the VCO. Both the UBA2213 and UBA2212 have a smooth transition from boost to lamp operation as can be seen in the lower image.
