1. General description
The TEA1703TS is a low power standby controller IC intended to be used in applications
which require an extreme low no-load standby power.
The TEA1703TS includes circuitry for detecting output voltage, output power and

7. Functional description
7.1 General control
The TEA1703TS contains a standby controller for switched-mode power supplies. Typical
configurations are shown in Figure 3 and Figure 4.
Typically the TEA1703TS senses the output voltage and output power of a switched-mode
power supply. The output voltage is sensed using a resistive divider network connected to
the VSENSE pin. The output power is sensed by determining the switching frequency of
the converter using an external filtering network. The converter output power is dependent
on the switching frequency, such as in a discontinuous conduction mode flyback converter
which has a fixed primary peak current during low load operation.
The TEA1703TS can be used in combination with a TEA1753 flyback controller. The
TEA1753T VINSENSE pin can be used to enter Standby mode. However, the VINSENSE
pin is also used to reset a latched protection in the TEA1753T. The TEA1703TS has an
integrated switching detection circuit which prevents unintentional resetting of a latched
protection.
When the TEA1753T is not switching, the TEA1703TS does not activate Standby mode.
Switching is detected using the SWDET pin as shown in Figure 3.
When configured with the TEA1733, switching detection is only required if the
primary-side VCC (TEA1733 VCC pin) is discharged below the latched protection reset
level. In Figure 4 a Zener diode Z1 is connected in series with the NPN transistor Q1
which discharges VCC on the VCC pin. The Zener diode is chosen to keep VCC on the
VCC pin just below the TEA1733 VCC start-up level while the application is in Standby
mode, guaranteeing a short restart time. If the Zener diode is omitted, connect the
switching detection input as shown in Figure 4. Otherwise connect the SWDET pin using
a series resistor to a fixed voltage.
The TEA1703TS has an open-drain optocoupler driver output with an integrated
freewheeling diode to the VCC pin. The optocoupler is efficiently driven in pulse mode
which ensures that the optocoupler Current Transfer Ratio (CTR) remains high; see
Section 7.7 and Section 7.8.

7.2 Standby mode operation
When the output load of the switched-mode power supply falls, the voltage on the
PSENSE pin also falls. When the voltage on the PSENSE pin is < Vth(PSENSE), the
TEA1703TS activates the OPTO pin output when the SWDET pin current is > Ith(det)sw.
When the OPTO pin output is activated in a typical application, the TEA1703TS disables
the switched-mode power supply. The output voltage starts to fall. After a period
dependent on the connected output power and the output capacitor value, the VSENSE
voltage falls below the Vth(VSENSE) level. The OPTO pin output is then disabled again. This
function restarts the primary-side converter.
If the output power remains low, the application reverts to Standby mode again after the
output capacitor has been recharged. When a normal load is detected, the converter
resumes normal operation; see Figure 5.

7.3 Voltage sensing (pin VSENSE)
If the voltage on the VSENSE pin is > Vth(VSENSE), the VSENSE pin outputs a current
IO(VSENSE). This current in combination with the external resistive divider, creates a
hysteresis on the adapter output voltage level. In a typical application, the effective output
voltage hysteresis is larger than that set by IO(VSENSE) and the resistive divider. This is
because the external PSENSE filter circuit keeps the PSENSE voltage > Vth(PSENSE) when
the output capacitor is not charged up to the normal output voltage level.

7.4 Power sensing (pin PSENSE)
Output power sensing is implemented using an external filter network on the PSENSE pin.
The PSENSE input is not latched internally. If, during Standby mode, the PSENSE pin is
pulled above the Vth(PSENSE) level, the OPTO output is disabled. The hysteresis on the
PSENSE pin makes the system less sensitive to voltage ripple.
7.5 Switching detection (pin SWDET)
A switching detection pin is provided to prevent applications resetting a latched protection
of the primary-side converter, such as the TEA1753. The Standby mode can only be
activated when the current into the SWDET pin is above the Ith(det)sw level.
The SWDET signal is latched internally. As soon as the OPTO output is activated, the
SWDET signal is ignored.
If the SWDET input is not needed, it can be connected to the VCC pin using a series
resistor. The current into the SWDET pin must be above the Ith(det)sw level when the
switched mode power supply is in normal operation.
7.6 Optocoupler output (pin OPTO)
The optocoupler output is an open-drain output with an integrated diode connected to
pin VCC. The output is driven with a fixed frequency (fosc,) and a fixed on-time (ton(OPTO)).
The optocoupler diode current can be set by choosing the value of the series inductor.
The current is not limited internally.
7.7 Optocoupler CTR
The CTR of a typical optocoupler falls significantly when small opto-diode currents are
used. With low optocoupler output currents, a higher diode current is needed for a typical
low-cost optocoupler.
In low Standby power operation of the switched-mode power supply, it is necessary to
keep all currents low. To maintain a high CTR, the optocoupler diode can be driven with a
high current and a small duty cycle. The average driving current is still low.
Figure 6 shows that a typical optocoupler CTR plotted for a DC-driven opto-diode and a
pulse-driven opto-diode. The pulse-driven diode is driven with a 2 mA duty cycle
modulated current. The CTR remains high, even for a very small average diode current
(low duty cycle) when the diode is pulse-driven, while the CTR for a DC-driven
optocoupler falls to a few percent.

7.8 Optocoupler drive
If a series resistor is used to limit the optocoupler diode current and the output voltage of
the application is 19 V, about 95 % of the driving energy is lost in the series resistor. The
efficiency to drive the optocoupler is therefore not more than about 5 %.
In the intended application, the optocoupler is active in Standby mode. Therefore, the
energy to drive the optocoupler must be as low as possible.
To improve the efficiency of the optocoupler drive, the optocoupler diode can be driven
with a series inductor. The optocoupler diode is then driven like a switched-mode power
supply2. Driving the optocoupler with a series inductor improves the efficiency by a factor
of 10 compared to driving it with a series resistor.
