Functional Description and Operation (cont’d)
Over-Voltage Protection Circuit
This feature of the STR-F66xx triggers the latch circuit
when the V
IN
voltage (pin 4) exceeds 22.5 V (typ.).
Because the voltage on pin 4 is proportional to the output
voltage (they are linked by the transformer turns ratio), the
regulator protects the output against over-voltage. This
function is entirely independant of the output-voltage
regulation loop and indeed will protect against output
over-voltage should the voltage error signal be lost. The
measure of over-voltage is given by:
V
OUT(OVP)
= V
OUT(NOM)
x V
IN(OVP)
/V
IN(NOM)
where V
IN(OVP)
is the drive voltage on pin 4.
In an over-voltage sensitive application, the drive
voltage can be set to close to 20 V and thus will protect the
output, if it rises more than 10% above nominal.
