• Taping(500 pieces)
OUTPUT VOLTAGE CONTROL
[EXTERNAL APPLIED VOLTAGE METHOD]
An external voltage is applied by the external circuit below. This
controls the output voltage(Vout).
R1
External voltage
+ D1 R2
Vs
C1 –
Vout=[0.5769–(External voltage–0.75)/R2]×68+0.75
Voltage: V
Resistance: kΩ
R1, C1: For removal of line noise
D1: Fast recovery diode
The external voltage range should be determined by the
following expression:
External voltage<R2×1mA+2.5(Unit: V)
[EXTERNAL RESISTANCE METHOD]: Refer to OUTPUT
VOLTAGE VARIABLE CHARACTERISTICS
An external resistance RA is placed between terminal No.
5(Vout) and No.6(Vset). This controls the output voltage(Vout).
Voltage changes per the following equation.
Vout=0.5769×[68×RA/(69.3+RA)]+0.75
Voltage: V
Resistance: kΩ
Recommended resistance range is 100 to 1000 kΩ.
RECOMMENDED SOLDERING CONDITIONS
Method: Infrared(or hot air) reflow method
Reflow temperature and time : 230°C max., 5s min.
: over 200°C, 40s min.
Preheating temperature and time: 130 to 160°C, 90s min.
Reflow cycle: 1 time(Vibrations should be avoided during reflow.)
PRECAUTIONS
• Install the components according to CIRCUIT DIAGRAM.
• This product operates only after the input-capacitor is
connected.
• Parallel operation to increase output current is not possible.
• Input fuse
A fuse should be connected to the input with a current rating 3
times that of the rated(normal) input current.
All specifications are subject to change without notice.
