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
shown in the right figure.
The right figure is an example using fuse and diode.
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 as it 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
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
This product can not be washed whole. No-clean solder paste is
recommend for this product.
Only for SIP type and DIP type, if cleaning is necessary, use IPA and
handwash the soldered surface by brush cleaning.
And after cleaning, dry sufficiently before using this product.
Solder under the following conditions.
1. With soldering iron
2. With soldering dip
3. Reflow method (only for SMD type)
By using this ON/OFF control function, ON/OFF control can be secured in the
output 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.
Do not use the ON/OFF function, keep ON/OFF pin open.
Between ON/OFF pin (1Pin) and S.GND (5-8Pin)
