Remote ON/OFF Control
- ON/OFF Function
- Not using ON/OFF Function
- Method of ON/OFF Control
To prevent reverse connection of Input Power Supply (ex.)
This prodcut is a non-isolated type DC-DC converter that steps-down
from (+) to (+).
If you connect the input voltage reversed by mistake,
it will be damaged.
If there is a possibility of reverse connection, please
add a protection as the right figure.
The right figure is an example using huse and diode.
Over-Voltage Protection (ex.)
Note2: When there is a ON/OFF function on the supplying power side,
Note 3: Be sure that the DC power supply on the supplying side has
Soldering Conditions
3. Reflow method (only for SMD type)
To not use the ON/OFF function, keep ON/OFF pin open.
Between ON/OFF pin
Open ---- Output=ON
This product does not have a built-in over-voltage protection.
If the switching element in this converter is damaged in short mode
input voltage +Vin will be output as is.
However, to prepare for damage at over-voltage mode, we recommend to
add a circuit to intercept the supplying power circuit.
Note1: When it is damaged at over-voltage mode, ON/OFF control does
Solder under the following conditions.
1. With soldering iron
2. With soldering dip
Short ---- Output=OFF (0~0.7V 1•A max.)
By using this ON/OFF control function, the output can be ON/OFF controlled without intermitting input.
This is an effective function when composing a power supply system sequence. And this can also be used as a power standby function for
saving power control.
Preheating Temp.: 150±10°C, within 1min.
Main heating temp.: 235°Cmax. 10sec max.
Reflowing frequency: once
