ISOLATION SPECIFICATION Input to Output Isolation: 1500Vdc (1 minute) SAFETY APPROVAL The AUM (10W) is certified under the following agencies: • UL/cUL 1950, and CE Mark. The module shall not be considered approved and carry safety agency logos until this has been authorized by Safety and QA / QC management. MODEL : AUM 10W SERIES April 05 REVISION 02 SHEET 5 OF 15 Technical Reference Note Ultra Low Profile AUM 10W Series 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.

Do not use acid or soluble flux, because they may damage metallic parts and glass parts and may cause defective or reduce quality. 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 Peak temperature : 240 ± 5 deg C at surface. Maximum period above 220deg.C : 20 – 60sec Ramp rate : lower than 4 deg C / sec Times : Max 2 times (see below recommendation) . Recommendation Do not give vibration to products while solder melts under reflow process. Please handle to wait for products cooled down enough. Please don’t reflow a motherboard mounted the products on the lower side such as a below figure, because the products surely fall down from the motherboard. Motherboard Isolated DC-DC converter Recommend Storage Condition Maximum storage period: Storage condition: 6 months 30 deg C, 60%RH Recommend baking the module at 100degC for 24 hours if storage period is longer than 6 months.
