After rejected the abnormal mode, DC-DC converter will automatically restart. However output short voltage affect long-term reliability. Thermal Derating Condition The output current is limited by the derating curve. The derating curve in this datasheet illustrate typical operation under a variety of conditions. DC-DC Converter is tested on a 101.6x188mm, 2 layers Copper evaluation board at Vin=48V. The Unit Under Test (UUT) is set up as shown below. UUT is covered by acrylic box to avoid airflow. The temperature measurement points are shown below table. The temperature of measurement points should not exceed the maximum temperatures in the below table. External Input Capacitor Do not connect any capacitor between positive input and negative input to avoid large inrush current. It is one of the requirements of IEEE802.3af standard.

When DC-DC converter(PD) is connected to PSE, the PSE applies two voltages in the range of 2.8 V to 10 V and measures the corresponding current. Connection to PD is detected by measured current.(Detection) After Detection, the PSE applies voltage in the range of 15.5 V to 20.5 V and measures the corresponding current. PD is classified by measured current.(Hardware Classification) Please check with your application. SMT Reflow Soldering Guidelines The surface-mount reflow solder profile is shown below.
