Short Description of the Pin Functions
Pin
Function
1
A parallel RC-circuit between this pin and ground determines the ringing
suppression time and the standby-frequency.
2
A capacitor between this pin and ground and a resistor between this pin and
the positive terminal of the primary electrolytic capacitor quantifies the max.
possible output power of the SMPS.
3
This is the input of the error amplifier and the zero crossing input. The output
of a voltage divider between the control winding and ground is connected to
this input. If the pulses at pin 3 exceed a 5 V threshold, the control voltage at
pin 4 is lowered.
4
This is the pin for the control voltage. A capacitor has to be connected
between this pin and ground. The value of this capacitor determines the
duration of the softstart and the speed of the control (primary regulation).
5
If an opto coupler for the control is used, its output has to be connected
between this pin and ground. The voltage divider at pin 3 has then to be
changed, so that the pulses at pin 3 are below 5 V.
6
Fault comparator 2: A voltage > 1.2 V at this pin stops the SMPS (v.also pin 9).
7
If fixed frequency mode is wanted, a parallel RC circuit has to be connected
between this pin and ground. The RC-value determines the frequency. If
synchronized mode is wanted, sync pulses have to be fed into this pin.
8
TDA 16846-2: Not connected. TDA 16847-2: This is the power measurement
output of the Temporary High Power Circuit. A capacitor and a RC-circuit has
to be connected between this pin and ground.
9
Output for the reference voltage (5 V). With a resistor between this pin and
ground the fault comparator 2 (pin 6) is enabled.
10
Fault comparator 1: If a voltage > 1 V is applied to this pin, the SMPS stops.
11
This is the input of the primary voltage check. The voltage at the anode of the
primary electrolytic capacitor has to be fed to this pin via a voltage divider. If
the voltage of this pin falls below 1 V, the SMPS is switched off. A second
function of this pin is the primary voltage dependent fold back point correction
(only active in free running mode).
12
Common ground.
13
Output signal. This pin has to be connected via a series resistor to the gate of
the power transistor.
14
Connection for supply voltage and startup capacitor. After startup, the supply
voltage is produced by the control winding of the transformer and rectified by
an external diode.
