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.

7. 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.

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:

f osc ( nom ) = ------------------------------------------k osc × R osc × C osc

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.

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.

7.6 Ignition state
The ignition state is entered after the preheat state has finished. 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:

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).

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.
