TDA 4601
Notes on Application Circuit 2
Wide Range SMPS
Filtering of the rectified AC-voltage has been increased up to 470
μ
F to ensure a constant and hum-
free supply at
V
line
= 80 Vac. The stabilized phase is tapped for supplying the IC. In order to ensure
good start-up conditions for the SMPS in the low voltage range, the non-stabilized phase of winding
13/15 is used as a starting aid (BD 139), which is turned off after start-up by means of Z-diode
C
12
.
In comparison to the 220 Vac standard circuit, however, the collector-emitter circuit had to be
altered to improve the switching behavior of BU 208 for the entire voltage range (80 to 270 Vac).
Diode BY 231 is necessary to prevent inverse operation of BU 208 and may be integrated for
switching times with a secondary power < 75 W (BU 208 D).
Compared to the IC TDA 4600-2, the TDA 4601 has been improved in turn-off during under-voltage
at pin 5. The TDA 4601 is additionally provided with a differential amplifier input at pin 5, enabling
precise turn-off at the output of pin 8 accompanied by hysteresis. For wide range SMPS, TDA 4601
is recommendable instead of TDA 4600-2. If a constant quality standard equal to that of the
standard circuit is to be maintained, wide range SMPS (80 to 270 Vac) with secondary power of
120 W can only be implemented at the expense of time.
