Functional description 7.1 Supply voltage The UBA2212 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. The half-bridge starts switching causing the charge pump to generate the required VDD supply. The amount of current flowing towards VDD equals VHV CDVDT f where f represents the momentary frequency. The charge pump consists of an external half-bridge capacitor (CDVDT). The IC contains two internal diodes with an internal Zener diode. The Zener diode ensures the VDD voltage cannot rise above the maximum VDD rating. The DVDT supply has its own ground pin (PGND) to prevent large peak currents from flowing through the external small signal ground pin (SGND). The start-up current source is enabled when the voltage on pin VDD is below VDD(stop). 7.2 Start-up state When the supply voltage on pin VDD increases, the IC enters the start-up state. In the start-up state, the High-Side Power Transistor (HSPT) is switched off and the Low-Side Power Transistor (LSPT) is switched on. The circuit is reset and the capacitors on the bootstrap pin FS (Cbs) and the low-voltage supply pin VDD (CVDD) are charged. Pins RC and SW are switched to ground. When pin VDD is above VDD(start), the start-up state is exited and the preheat state is entered. If the voltage on pin VDD falls below VDD(stop), the system returns to the start-up state. Remark: If OTP is active, the IC remains in the start-up state for as long as this is the case. The VDD voltage slowly oscillates between VDD = VDD(stop) and VDD = VDD(start). 7.3 Reset A DC reset circuit is incorporated in the high-side driver. The high-side transistor is switched off when the voltage on pin FS is below the high-side lockout voltage. 7.4 Oscillation control The oscillation frequency is based on the 555-timer function. A self oscillating circuit is created comprising the external components: resistors Rosc, RSENSE and capacitor Cosc. Rosc and Cosc determine the nominal oscillating frequency. An internal divider 0.5 fosc(int) is used to generate the accurate 50 % duty cycle. The divider sets the bridge frequency at half the oscillator frequency. The input on pin SW generates signal VSW. The VSW signal is used to determine the frequency in all states except preheat. Signal VCB is an internally generated signal used to determine the frequency during the preheat state.

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.

Oscillator, HSPT/LSPT drivers and output signals 7.5 Preheat state The VCO input is directly connected to a fixed DC voltage of 0.3 V in the preheat state. The frequency is set to about 0.94 fmax to ensure voltage mode preheat. The preheat state is finished when VSW drops to 0.3 V. 7.6 Ignition state The ignition state is entered after the preheat state has finished. Current ISW charges the capacitor on pin SW (CSW) and the frequency continuously drops. During this frequency sweep (fSW), the resonance frequency is reached resulting in the ignition of the lamp (see Figure 5). The lamp inductor (Llamp) and lamp capacitor (Clamp) set the resonance frequency. UBA2212 Product data sheet All information provided in this document is subject to legal disclaimers.

VCB VSW VCO input time (s) preheat steady ignition and boost transition Fig 5. aaa-002682 Vlamp, fosc(int), VCB and VSW plotted against time 7.7 Boost state and transition to steady state The boost state is entered after ignition. The output of RMS current control circuit and the input of VCO are switched to capacitor CSW. At the same time, the input of RMS current control circuit is switched to pin CSI to sense lamp current. On pin CB, capacitor CCB is connected to the boost timer input to control the boost time. VSW changes to a given voltage to set the lamp current to the level pre-defined by the internal boost reference and resistor RCSI. The calculation is shown in Equation 2: V ref bst Boost I lamp = -----------------R CSI (2) When boost timer gives a signal to indicate that boost state is ended, the transition from boost to steady state starts to avoid flicker. In this state, the boost transition timer is active to define the transition time, which is also realized with capacitor CCB on CB pin. 7.8 Steady state When the RMS current control circuit leaves the system operating at the normal lamp current, it enters the steady state. In this state, the voltage on pin CB is fixed and the voltage on pin SW is controlled by a feedback loop. This feature enables the lamp current to be independent of the mains or lamp voltage. The same analysis as with the boost state can be used to express lamp current (Equation 3): V ref steady Steady I lamp = ------------------------R CSI UBA2212 Product data sheet All information provided in this document is subject to legal disclaimers.

The non-overlap time is fixed internally and is fixed at the tno value (see Table 5). 7.10 OverTemperature Protection (OTP) OTP is active in all states except boost. When the die temperature reaches the OTP activation threshold (Tth(act)otp), the oscillator is stopped and the power switches (LSPT/HSPT) are set to the start-up state. When the oscillator is stopped, the DVDT supply no longer generates the supply current IDVDT. Voltage VDD gradually decreases and the start-up state is entered as described in Section 7.2 on page 5. OTP is reset when the temperature < Tth(rel)otp. During boost state, the threshold of temperature is Tj(end)bst which is lower than Tth(otp). When the die temperature has reached Tj(end)bst, the boost state ends, the IC enters steady state and OTP is enabled. 7.11 Saturation Current Protection (SCP) A critical parameter in the design of the lamp inductor is its saturation current. When the momentary inductor exceeds its saturation current, the inductance drops significantly. The inductor current and the current flowing through the LSPT and HSPT power switches increases rapidly if this happens. The increase can cause the current to exceed the half-bridge power transistors maximum ratings. Saturation of the lamp inductor is likely to occur in cost-effective and miniaturized CFLs. The UBA2212 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 CSW). This function causes the system to balance at the edge of the current rating of the power switches. 7.12 Capacitive Mode Protection (CMP) In boost and steady state, VSW determines the operating frequency. The RMS current control circuit and the CMP circuit control this frequency. When Capacitive mode is detected, capacitor CSW is mainly controlled by the CMP circuit. Capacitor CSW is discharged by a current source, which is also dependent on the hard switching voltage level. The operating frequency fosc, increases until CMP is no longer detected. Remark: CMP always controls the operation. If the lamp current is lower than the defined value before CMP is detected, the system moves to the edge of hard switching (~25 V). The set value cannot be achieved. Change the LC tank to get a higher resonant gain, which enables the required lamp current to be obtained.
