UBA2211 NXP Semiconductors Half-bridge power IC family for CFL lamps 7. Functional description 7.1 Supply voltage The UBA2211 family is powered using a start-up current source and a DVDT supply. When the voltage on pin HV increases, the VDD capacitor (CVDD) is charged using the internal Junction gate Field-Effect Transistor (JFET) current source. The voltage on pin VDD rises until VDD equals VDD(start). The start-up current source is then disabled.

UBA2211 NXP Semiconductors Half-bridge power IC family for CFL lamps The output voltage of the bridge changes with the falling edge of the signal on pin RC. The nominal half-bridge frequency is shown in Equation 1: 1 f osc  nom  = ------------------------------------------k osc  R osc  C osc (1) The maximum frequency is 2.5  fosc(nom) and is set at VSW. An overview of the oscillator, internal LSPT and HSPT drive signals and the output is shown in Figure 4.

UBA2211 NXP Semiconductors Half-bridge power IC family for CFL lamps During the other oscillator clock cycle, the input of the squarer is connected to the internal reference voltage VO(ref)RMS. This voltage is squared and converted into a negative current. This charge current is also added to capacitor CSW.
