... NXP Semiconductors 7. Functional description 7.1 Supply voltage The UBA2211 family is powered using the start-up current source and the V When the voltage on pin HV increases, the V internal Junction gate Field-Effect Transistor (JFET) current source. The voltage on pin V rises until V DD half-bridge starts switching causing the charge pump activate and in turn supply V The amount of current flowing towards V momentary frequency ...

... The R SENSE ratio between them is fixed. However by adding a resistor in parallel to C this ratio can be adjusted. This is described in more detail in the UBA2211 user manual. 7.8 Non-overlap time The non-overlap time is defined as the time when both MOSFETs are not conducting. The non-overlap time is fixed internally. ...

... Saturation of the lamp inductor is likely to occur in cost-effective and miniaturized CFLs. The UBA2211 family internally monitors the power transistor current. When this current exceeds the momentary rating of the internal half-bridge power transistors, the conduction time is reduced and the frequency is slowly increased (by discharging C the system to balance at the edge of the current rating of the power switches ...
