TEA2164S
I - FIELD OF APPLICATION
The TEA2164S control circuit has been designed
primarily for discontinuous mode flyback built with
a master-slave architecture, whatever the field of
application.
But due to its capability to synchronize the transistor switching-off with an external signal (line flyback) and due to an adaptedburst-mode operation
for a low power stand-by operation, the TEA2164
offers a smart solution for monitors and TV sets
applications.
Power supply main features :
- maximum output power 140W (transistor forced
gain : 3.5)
- stand-by mode output power (1W ≤ Psb ≤ 6W ;
efficiency > 50%)
- operating frequency up to 50kHz
- power-switch : bipolar transistor
Adapted master-circuit :
- Monitor application
→ TEA5170
- Standard TV application → TEA2028B
TEA2029C
TEA2128
TEA5170
- Digital TV application
→ TEA5170
(TEA2028B, TEA2029C and TEA2128 are deflection processors with built-in PWM generator).

II - GENERAL DESCRIPTION
In a master slave architecture,the TEA2164SControl IC, located at the primary side of an off line
power supplyachievesthe slavefunction; whereas
the master circuit is located at the secondary side.
The link between both circuits is realizedby a small
pulse transformer (Figure 4).
The PWM signal are sent towards the primary side
through small differentiating transformer. For the
TEA2164Spositive pulses are transistorswitchingon commands ; and negative pulses are transistor
switching-off commands (Figure 5). In this configuration, only by synchronizing the master oscillator,
the switching transistor may be synchronized with
an external signal.
In the operation of the master-slave architecture,
four majors cases must be considered :
- normal operating
- stand-by mode
- power supply start-up
- abnormal conditions : off load, short circuit, ...
II.2 - Stand-by Mode
In this configuration the master circuit no longer
sends PWM signals, the structure is not synchronized ; and the TEA2164Soperates in burst mode.
The average power consumption at the secondary
side may be very low 1W ≤ P ≤ 6W (as it is
consumed in TV set during stand by).
By action on the maximum duty cycle control, a
primary loop maintains a semi-regulation of the
output voltages.Voltage on feed-backis applied on
Pin 9.
BurstperiodisexternallyprogrammedbycapacitorC1.
II.1 - Normal Operating (master slave mode)
In this configuration,the master circuit generates a
pulse width modulatedsignal issued from the monitoring of the output voltage which needs the best
accuracy (in TV applications : the horizontal deflectionstage supply voltage). Themaster circuit power
supply can be supplied by another output.

II.3 - Power Supply Start-up
After the mains have been switched-on, the VCC
storage capacitor of the TEA2164S is charged
through a high value resistor connected to the
rectified high voltage.
When Vcc reaches VCC start threshold (9V typ), the
TEA2164 starts operating in burst mode. Since
available output power is low in burst mode the
output power consumption must remain low before
complete setting-up of output voltage.
In TV application it can be achieved by maintaining the TV in stand-by mode during start-up
(Figure 7).

II.4 - Abnormal conditions : safety functions
Overvoltage Protection
When VCC exceeds VCC max, an internal flip-flop
stops output conduction signals. The circuit will
start again after the capacitor C1 discharge ; it
means : after loss of synchronization or after VCC
stop crossing (Figure 8).
In flyback converters, this function protects the
power supply against output voltage runaway.
Under Voltage Lock-out
The TEA2164S control circuit stops operating
when VCC goes under VCC stop.
Power Limitation, Current Protection, Long
Duration Overload Protection
- Output power limitation : by a pulse by pulse
collector current limitation the TEA2164S limits
the maximum output power. VCM1 is the corresponding voltage threshold, its detection is
memorized up to the next period.
- Current protection (transistor protection)
Under particular conditions a hard overload or
short circuit may induce a flux runaway in spite of
the current limitation (VCM1).
The TEA2164S control circuit features a second
8/16
current protection, VCM2. When this threshold is
reached an internal flip-flop memorizes it and
output conduction signals are inhibited. The circuit will send base drives again after capacitor C1
discharge (Figure 8).
- Long duration overload protection : (Figure 9)
An overload is detected when the sense-voltage
on Pin 11 reaches VCM3 before a negative pulse
has been applied to Pin 6. In this case the capacitor C2 (connected to Pin 3) is charged with I3 ch
up to the end of the period and discharged with
I3 disch until a next VCM3 detector. By this way in
case of long duration overload, the capacitor
keeps charging at each period and its voltage
encreases gradually. When the voltage on Pin 3
exceeds VC2, the TEA2164S control circuit stops
sending base drives and memorizes this event.
No restart is allowed as long as Vpin 3 is higher
than VC2 and VCC higher than 4.8V.
* Remark :
- The harder is the overload the faster is the protection
- The capacitor keeps charging between two burst
after VCM2 detection.

III - SWITCHING OSCILLATOR AND SYNCHRONIZATION
III.1. Switching oscillator
When the TEA2164S control circuit operates in
burst mode, the switching frequency is fixed by the
free frequency oscillator. The period is determined
by two external components CO and RO.
In order to avoid any erratic conduction of the
power transistor, the first synchronizationpulse will
arrive simultanously with the sawtooth return of the
TEA2164S oscillator.
To get synchronization the free frequency must be
higher than the synchronization frequency.
III.2. Synchronization
When the master-circuit starts to send pulses both
oscillators are not synchonuous.

IV - MAXIMUM DUTY CYCLE LIMITATION
Burst mode : The maximum duty cycle is controlled
by the voltage on Pin 9 (Figure 15).
Synchronized mode : Normally the maximum duty
cycle is set by the master circuit. However the
maximum conducting time will never exceed the
value given by the comparison of the oscillator
wave-form with the 2.5V internal threshold.
- After the starting pulse I BON, the base current is
proportional to the collector current. The current
gain is easily fixed by a resistor RB (Figure 16).
- A fast and safe transistor turn-off is realized by a
fast positive base current cut-off and by applying
a negative base drive which draws stored carriers. Atypical 0.7s delay prevents from cross-conduction of positive and negative output stages.
V - OUTPUT STAGE
TEA2164S output stage has been designed to
drive switching bipolar transistor.
- Each base drive begins with a positive pulse IBON
that realizes an efficient transistor turn-on.
Remark : In order to reduce power dissipation on
the positive output stage with the low gain transistors, for high base currents the positive output
stage operates in saturated mode (Figure 17). This
can be achieved by using a resistor between VCC
and V+.

VI - MONITOR APPLICATIONS
In most of monitor applications, the power supply must start-up under full load conditions and the stand
-by mode is no longer useful.
The energy of the starting burst must be high enough to ensure start-up, then the capacitor C1 must be
higher in these applications than on TV application (typ. : 1µF).
