5. Absolute Maximum Ratings
Input Voltage +45V
※No voltage, no matter how instantaneous, shall be applied beyond the absolute maximum voltage rating to
this product. If you apply any voltage over this limit the product characteristics will deteriorate or the product
itself will be destroyed. Even though it may continue operating for a while after the over-voltage event,
it’s life will likely be shortened significantly.Reliability and life of the module may degrade similarly
if the maximum operating voltage rating is continuously exceeded.
This product is designed to operate within the maximum operating voltage rating specification.

12. Notice
12.1. Input / Output capacitor
When a inductance or a switch devise are connected to the input line, or when you use a power supply with
output inductance as the input voltage source, the input voltage of the DC-DC converter will be fluctuated.
By this input voltage fluctuation, the transient load response of the DC-DC converter may be deteriorated or
abnormal oscillation may occur. So please confirm normal operation on each application.
Please use external input capacitor in order to decrease inductance of input line.
In case you use external output capacitor in order to improve transient load response, please use input
capacitor to prevent abnormal oscillation. When you use external capacitors, following capacitors are
recommendable.
Output capacitor: Please use capacitors less than 680μF
12.2. Wiring of input / output capacitor
In the case of input / output capacitor connection, in order to reduce electrical noise, please design PCBs
with consideration of the following item.
①.Please be sure to check normal operation on your system.
②.Please use low impedance capacitors with good high frequency characteristic.
③.Please shorten those leads of each capacitor as much as possible, and make sure the lead
Inductance low.
④.Both input-side and output side, please make the wiring loop between plus and minus as small as
possible.The influence of leakage inductance can be reduced.
⑤.Please design the print pattern of the main circuit as wide and short as possible.

12.7. Please connect the input terminals with the correct polarity. If you connect this by mistake, it may break
the DC-DC converter. In the case of destruction of the DC-DC converter inside, over input current may
flow, and so DC-DC converter maybe occurred abnormal temperature rise, or your product may be
damaged.Please add a diode and fuse per the following diagram to protect them.
