Ultra High Efficiency 82 - 91%
High Efficiency, Small, Low price, Step-Down DC-DC Converter
5 Watt VSA Series
<Soldering Conditions>
<Directions>
Solder to be executed under the following conditions.
1. Hand Soldering Condition 340°C to 360°C within 5sec.
2. Wavesoldering Condition 240°C to 260°C within 10sec.
For customer's safety, please see the specification and obey the
undermentioned notes definitely when using this product.
- This product intends to be used for a general electronic equipment
(Clerical work machine, Telecommunications equipment, and Measurement
equipment). Please do not use the medical equipment, the nuclear power
equipment, and the train, etc. with dread that the damage of this product
might influence the life and the property directly. Please confirm us when
you use except for the general electronic equipment.
<Cleaning Conditions>
This product can not be cleaned bodily and is recommended non-cleaned
- This product cannot be driven with parallel and series.
flax. When and if cleaning only for SIP and DIP type should be necessary, - Please use neither connector nor the socket to mount this product.
use IPA and hand-wash the soldered surface by brush cleaning.
After cleaning, please dry enough to use it.
The performance might not be able to be satisfied because of
the contact resistance. Please execute mounting on the printed wiring
board by soldering.
- Although the overcurrent and the short-circuit protection circuit are built
in this product, please avoid short-circuit for a long time as it causes
the breakdown.
- There is a possible to be damaged for this product if it is used in a non-
standard electric condition and an environmental condition etc. of the
temperature etc. Please use it in the standard.
- Please make the earth electrical discharge done, and work about worker's
electrified static electricity which might be damaged by static electricity
in the environment static electricity.
<To prevent reverse input voltage protection (ex.)>
The input/output of this products is a non-isolated type and a step-down
DC-DC converter from (+) polarity to (+) polarity. If you connect the input
polarity reversed of this product by mistake it will be eventually damaged.
If there is a possibility of reverse connection, please add a protection
circuit as indicated in the following figure. The figure below is an example
using huse and diode.
- This product does not built the fuse inside. When it is abnormal, please
connect the fuse with + input line as protection for an excessive current
flows to the input. Please give capacity by which the fuse can be cut to
the power supply.
- This product does not built in the overvoltage protection.
- When the overvoltage is abnormally generated in the module, there is
a mode that the input voltage appears to the output straight, and causes
smoking and the ignition. Please add the overvoltage protection circuit to
prevent it.
(Figure 7)
<Over-Voltage Protection (ex.)>
This product does not have a built-in over-voltage protection.
When the switching element of this converter gets damaged by short
mode, input voltage (+Vin) will go out on the output.
- The examination result is not attached to this product.
For emergency if it gets damaged at over-voltage mode, please add
a circuit as below to intercept the supplying power circuit.
<Guarantee>
The guaranteed term of this product is one year. During this period, if there
should be any failure definitely due to our designing or manufacturing
workmanship, we will repair or replace with new one at our own expense.
But in that case that you should modify and / or make internal remodeling
by itself whatsoever, we cannot guarantee it.
This guarantee shall cover only 5 Watt VSA series.
<Others>
We will decide upon both deliberations when the doubt is caused in this
catalog.
(Figure 8)
Notes:
When it is damaged at over-voltage mode, ON/ OFF control does not operate.
When there is a DC Power Supply on the supplying power side, please have the capacity the fuse can be cut.
