Data Sheet
Operation notes
(1) No circuit is installed in the modules to protect against excessive output currents. Therefore, take physical
safety measures such as using a fuse if short-circuit loading is probable.
(2) The output current should be reduced according to an increase in the input voltage or ambient temperature.
Use the modules within the derating curve range.
(3) A large rush current may flow in the module when the input voltage is applied or the output ON / OFF is
controlled with pin 4 without a capacitor such as C1 in application 4. Operating within the safe operation
ranges shown in Fig.12, 15, and 18.
The safe operation range is determined by the safe operation range of the internal switching transistor.
The amount of rush current depends on the output impedance of the input power supply and capacitors
connected to the module outputs. The pulse load on the internal switching transistor at the start of operation
can be reduced by using the protection circuit in application 1 or the slow start circuit in application 4.
(4) Pins 5 and 7 are not connected.
(5) A smoothing electrolytic capacitor is necessary for I/O external components. Please use a capacitor equivalent
to the recommended one.
(6) Please put an I/O smoothing capacitor near the module. Output ripple voltage may be larger or output voltage
may not be stable.
