SLB 0587
Application Circuit (Figure 4)
The suggested circuit design of the SLB 0587 performs the following functions:
G
Current supply for the circuits (
R
1
,
R
3
,
C
2
,
C
3
,
C
6
, D1, D2).
G
Filtered signal for synchronization of the internal time base (PLL circuit) with line frequency
(
R
2
,
C
4
).
G
For specific applications
C
4
and
R
2
can be varied according to
figure 5
. An increase for
C
4
and
R
2
causes a slight reduction of the lamp brightness but at the same time an im-
provement of interference immunity of the internal PLL against line voltage spikes.
G
Integration unit for internal PLL circuit (
C
5
,
R
10
)
Combining
R
10
and
C
5
(figure 6)
determines within certain limits the following factors
– Start-up behaviour of internal PLL after line failure
– Ripple control behaviour (periodic shifts of lamp brightness if ripple control signals
represent)
G
Protection of the user (
R
8
,
R
9
)
G
Sensitivity setting of the sensor (
R
7
)
G
Current limitation in the case of reverse polarity of the extension (
R
5
,
R
6
)
Both resistors can be omitted if no extension is connected. In this case pin 6 must be con-
nected to
V
SS
(pin 7).
G
D3: Reduction of positive voltages which may arise during the triggered state at the gate of
some triacs, to values below
V
DD
+ 0.3 V by diode forward voltage. If suitable triacs are used,
diode D3 can be omitted.
G
Dr, C
1
are used for EMI suppression.
Depending on the application the EMI suppression is to be dimensioned in acc. with
VDE 0875/part 1 (general)
VDE 0550/part 6 (chokes)
or corresponding the national regulations e.g. 1.4....2 mH, Q = 11....24
