Basic Operation and Features
Over Current Limit Inception (OCP)
The Isolated DC-DC converter limits output current when the current is over the maximum output current due to
abnormality such as overload or short circuit. When over current condition continues and output voltage decreases to the
point of low voltage protection, the DC-DC converter will be in latch up mode. To restore the output, remove the
abnormality and re-set the input voltage under 5V for 1 second minimum.
Over Voltage Protection (OVP)
The Isolated DC-DC converter stops the operation when the output voltage is over the specified Over Voltage Protection
point, the converter will be in latch up mode after 0.5ms*. To restore the output, re-set the input voltage under 5V for 1
second minimum.
Notes*: Output voltage might exceed the point at which OVP starts to function under the specific condition of transient
input voltage or output current change. Therefore, OVP is set to wait for the mask time 0.5ms.
Low Voltage Protection (LVP)
If output voltage is under the specified Low Voltage Protection point, the converter will halt the operation. After typical
500ms mask period, the converter will be in latch up mode. To restore the output, re-set the input voltage under 5V for 1
second minimum.
Remote On/Off Control (RC)
If RC pin is open or connected to –Vin, the converter is turned on. If RC is connected to +Vin, the converter is turned off.
Alarm Output (ALM)
The Alarm output will be down to the –Vin level (Open Drain Output) at the condition of Over Voltage Protection or Low
Voltage Protection. The maximum sink current in ALM pin is 10mA. When operating in parallel application, all operating
units can be simultaneously halt by connecting all the ALM pins together, in the condition of Over Voltage Protection or
Low Voltage Protection caused by any single converter. Maximum number for parallel operation is 10 units
Synchronous Turn On/Off
Connect the PO (parallel Operation) pins of all operating units together will synchronize the turn on / off time in parallel
application.

Reflow Soldering Information
Soldering
I) Flux
Solder the products with Rosin Flux (0.2wt%. chloride or less).
Do not use acid or soluble flux, because they may damage metallic parts and glass

II) Solder
SnAgCu solder compatible
III) Condition of Soldering – Recommended soldering profile (J-STD-020C):
Reflow Profile :
Infrared or air blow
Preheating
:
150 – 200 deg C for 60 to 150sec
