Protection Functions
The chip has several protection functions:
Current Limiting
See
“
Primary Current Simulation PCS (Pin 2) / Current Limiting
”
and
“
Fold Back Point
Correction PVC (Pin 11)
”
.
Over- and Undervoltage Lockout OV/SVC (Pin 14)
When
V
14
at Pin 14 exceeds 16 V, e. g. due to a fault in the regulation circuit, the Error
Flip Flop ERR is set and the output driver is shut-down. When
V
14
goes below the lower
SVC threshold, ERR is reset and the driver output (Pin 13) and the soft-start (Pin 4) are
shut down and actively held low.
Primary Voltage Check PVC (Pin 11)
When the voltage
V
11
at Pin 11 goes below 1 V the Error Flip Flop (ERR) is set. E.g. a
voltage divider from the rectified mains at Pin 11 prevents from high input currents at too
low input voltage.
Free Usable Fault Comparator FC1 (Pin 10)
When the voltage at Pin 10 exceeds 1 V, the Error Flip Flop (ERR) is set. This can be
used e. g. for mains overvoltage shutdown.
Free Usable Fault Comparator FC2 (Pin 6)
When the voltage at Pin 6 exceeds 1.2 V, the Error Flip Flop (ERR) is set. A resistor
between Pin 9 (REF) and ground is necessary to enable this fault comparator.
Voltage dependent Ringing Suppression Time
During start-up and short-circuit operation, the output voltage of the converter is low and
parasitic zero crossings are applied for a longer time at Pin 3. Therefore the Ringing
Suppression Time TC1 (see
“
Off-Time Circuit OTC (Pin 1)
”
) is made longer with
factor 2.5 at low output voltage. To ensure start-up of the circuit, the value of resistor
R
1
(Pin 1,
Figure 6
) must be higher than 20 k
.
