DESCRIPTION
In a master slave architecture, the TEA2164 control
IC achieves the slave function. Primarily designed
for TV receivers and monitors applications, this
circuit provides an easy synchronization and smart
solution for low power stand by operation.
Located at the primary side the TEA2164 Control
IC ensures :
- the power supply start-up
- the power supply control under stand-by condi-
tions
- the process of the regulation signals sent by the
master circuit located at the secondary side
- directbase drive of the bipolar switching transistor
- the protection of the transistor and the power
supply under abnormal conditions.
For more details, refer to application note AN409.

TEA2164
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.1. Normal Operating (master slave mode)
In this configuration, the master circuit generates a
pulse width modulatedsignal issued from the moni-
toring of the output voltage which needs the best
accuracy (in TV applications : the horizontal deflec-
tion stage supplyvoltage). The master circuit power
supply can be supplied by another output.
The PWM signal are sent towards the primary side
through small differentiating transformer. For the
TEA2164 positive pulses are transistor switching-
on commands ; and negative pulses are transistor
switching-off commands (Figure 4). In this configu-
ration, only by synchronizing the master oscillator,
the switching transistor may be synchronized with
an external signal.
II.2. Stand-by Mode
In this configuration the master circuit no longer
Figure 4 : Master Slave Mode Waveforms
sends PWM signals, the structure is not synchro-
nized ; and the TEA2164 operates 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-back is applied on
Pin 9.
Burst period is externally programmed by capacitor
C1.
II.3. Power Supply Start-up
After the mains have been switched-on, the VCC
storage capacitor of the TEA2164 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 6).
