10. Over-Voltage Protection Diagram (Ex.)
HIGH SPEED LOAD RESPONSE, OUTPUT VOLTAGE SETTING ACCURACY±1% POL DC-DC Converter
Note 1. When it is damaged at over-voltage mode,
ON/OFF control will not operate.
Note 2. When having ON/OFF function on the supplying
power side, this circuit can be used.
Note 3. Be sure that the DC power supply on the supplying
side has the capacity to cut the fuse.
11. Soldering Conditions
11-1. Reflow method
11-2. About storage before being mounted
This product does not have a built-in over-voltage protection.
If the switching element in this converter is damaged in short mode, DC input voltage will go out as output.
To avoid damage at over-voltage mode, in advance, please add the input interrupting circuit as below.
Please conduct by the condition as below regarding the soldering temperature and time and storage before mounting.
Pre-heating temp.: 150-180°C, within 60 sec max. (Refer to the figure below)
Peak heading temp.: 250°C max.
220°C or more, within 60 sec max.
Reflow: twice
Note 1. Do not give shock at reflow because components which compose the converter may move.
Note 2. After mounting the converter on PCB, please do not reflow again turning the PCB over.
When you open dry packing, storage conditions before being mounted should be 30°C/60% RH or below. Moreover,
baking (125°C±5°C, 12H) is needed before the reflow when exceeding one year in a dry pack and 168 hours at 30°C/60%
RH in an open dry pack conditions.
After mounting, it depends on the environmental condition.
