TYPICAL TEMPERATURE CURVE
1) Recommended circuit
If
you
may be
want
to
further
decrease
the
input/output
ripple,
an "LC" filtering
network
connected to the input and output ends of the DC/DC converter, see (Figure 1).
However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big,
a startup problem might arise. For every
channel of output,
provided
the safe
and
reliable
operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). General:
Cin:
5V,12V
24V,48V
100µF 10µF Cout:
47µF (Typ.)
Lin:
4.7µH-120µH Lout:
2.2µH-10µH Cs:
10µH-22µF 2) CTRL Terminal
When open or high
impedance,the converter work well; When
this pin
is "high"
the converter
shutdown; It should be note that the input current (Ic) should between 5-10mA,exceeding
the maximum
20mA will cause permanence damage to the converter. The value of R Can be derived as follows :
R=
V − V − 1 .0
Ic
3) Input current
While using unstable power source, please ensure the output voltage and ripple voltage do not
exceed
indexes
of
the
converter.
The
preceding
provide for converter sufficient starting current Ip (Figure 2).
General: Ip ≤1.4Iin-max

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise
specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
