UBA2211 Half-bridge power IC family for CFL lamps Rev. 2 — 3 January 2011 Objective data sheet 1. General description The UBA2211 family of integrated circuits are a range of high voltage monolithic ICs for driving Compact Fluorescent Lamps (CFL) in half-bridge configurations. The family is specifically designed to provide easy integration of lamp loads across a range of burner power and mains voltages. Patented technologies and integrated protection types: • Preheat state: – Preheat applications: Adjustable current controlled preheat mode technology enables the preheat time (tph) and preheat current to be set. This mode is triggered during start up. – Non-preheat applications: Glow-time control minimizes electrode damage just after ignition of the lamp. • Saturation Current Protection (SCP): This protection is active during ignition ensuring the lamp inductor can operate at the saturation current limit without exceeding the current ratings of the integrated half-bridge power transistors. • RMS current control: The IC internally calculates the RMS current and changes the frequency (fosc) to ensure the RMS current remains constant. RMS current control is active in the burn state ensuring a constant half-bridge burner current and IC dissipation. The nominal half-bridge burner current is set using the sense resistor (RSENSE). • OverTemperature Protection (OTP) and Capacitive Mode Protection (CMP): Overtemperature and capacitive mode protection monitor the application ensuring, in non-standard conditions, correct system shutdown and a safe condition at the burner’s end-of-life. 2.

Functional description 7.1 Supply voltage The UBA2211 family is powered using the start-up current source and the VDD 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 activate and in turn supply VDD. 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 SO14 package contains two internal diodes with an internal Zener diode. However, with the DIP8 package, these diodes must be mounted externally. 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. The nominal oscillating frequency is determined by Rosc and Cosc. 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. Signal VSW is generated by the input on pin SW and it is used to determine the frequency in all states except preheat. Signal VSW(ph) is an internally generated signal used to determine the frequency during the preheat state.

Objective data sheet Rev. 2 — 3 January 2011 5 of 19 NXP Semiconductors UBA2211 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.

Oscillator, HSPT/LSPT drivers and output signals 7.5 Preheat state As described in Section 7.2, the IC enters the preheat state when the voltage on pin VDD is above VDD(start) and OTP is not active. The capacitor on pin SW (CSW) is charged by the sweep current (ISW). The preheat Operational Transconductance Amplifier (OTA) is enabled and the half-bridge circuit starts oscillating. The preheat current is monitored using the external RSENSE resistor. The OTA controls the frequency using output voltage VSW(ph) so that the peak voltage across RSENSE equals the internal reference voltage (Vref(ph)). The peak voltage is the voltage at the end of the LSPT conduction time. The preheat peak current through the lamp filament is calculated as shown in Equation 2: V ref ( ph I ph ( peak ) = -----------------) R SENSE (2) The preheat time is set by the external capacitor (CSW). The preheat state ends when the down-going CSW voltage equals VSW(ph); see Figure 4. If during the preheat time, capacitive mode is sensed, the internal VSW HIGH node is discharged and the frequency sweep restarts at fmax.

The capacitor on pin SW (CSW) is charged by ISW up to 0.6 × VH(RC) which corresponds to the frequency fosc(nom). During this frequency sweep, the resonance frequency is reached resulting in the ignition of the lamp (see Figure 4). The resonance frequency is set by the lamp inductor (Llamp) and lamp capacitor (Clamp). The ignition state ends when the voltage on pin SW (VSW) reaches 0.6 × VH(RC). 7.7 Steady state In the steady state, the RMS current control is active. This control sets the frequency so that the RMS voltage across the sense resistor (RSENSE) is equal to VO(ref)RMS. This ensures the current through the power switches and through the lamp is constant. This results in constant IC dissipation and temperature at a fixed ambient temperature. During one oscillator clock cycle, the voltage on pin SENSE (VSENSE) is squared and converted into a positive current. This discharge current is added to the capacitor CSW. 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. When both currents are equal, then Equation 3 is true: UBA2211 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

Taking the square root of both sides results in Equation 4: T osc T osc 1 --------- × T osc or ∫ 0 V SENSE ( t ) DT 2 = 1 --------- × T osc ∫ 0 V O ( ref ) RMS DT 2 (4) RMS V SENSE = V O ( ref ) RMS = R SENSE × I LSPT (5) A constant current flows through the power switches and the lamp which is defined by the internal reference voltage (VO(ref)RMS) and the external RSENSE resistor. The RSENSE resistor sets both the preheat current and the RMS half-bridge current. The ratio between them is fixed. However by adding a resistor in parallel to Csw (see Figure 7) 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. 7.9 OverTemperature Protection (OTP) OTP is active in all states. 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 startup 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. 7.10 Minimum glow time control If the preheat time is set too short or omitted, the lamp electrodes do not have the correct temperature in the ignition state. This results in instant light but also in a reduced switching lifetime because when the electrode temperature is too low electrode sputtering and damage occur. The minimum glow time control minimizes electrode damage by ensuring maximum power use during the glow phase to heat the electrodes heat as quickly as possible (see Figure 6).

The glow time control is active as tph is too short to preheat the electrodes 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. If this happens, the inductor current and the current flowing through the LSPT and HSPT power switches increases rapidly. This 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 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 CSW). This causes the system to balance at the edge of the current rating of the power switches. 7.12 Capacitive Mode Protection (CMP) When capacitive mode is detected, capacitor CSW is discharged causing the frequency to increase. The system sets itself to the operating point where capacitive mode switching is minimized. CMP is active during the ignition state and in the steady state. If capacitive mode is sensed during the preheat time, the oscillator restarts at fmax. CMP could be triggered by an end of lamp life condition when a lamp electrode is broken.
