4. Thermal check – At maximum output power, minimum input  
voltage and maximum ambient temperature, verify that the  
LinkSwitch-TN2 SOURCE pin temperature is 100 °C or below.  
This ensures adequate margin due to variations in RDS(ON) from  
part to part. If the device temperature of the IC exceeds 85 °C  
with ambient temperature of 25 °C, it is recommended the next  
bigger device in the family should be selected for the application.  
A battery powered thermocouple meter is recommended to make  
measurements when the SOURCE pins are a switching node.  
Alternatively, the ambient temperature may be raised to indicate  
margin to thermal shutdown.  
Quick Design Checklist  
As with any power supply design, all LinkSwitch-TN2 designs should  
be verified for proper functionality on the bench. The following  
minimum tests are recommended:  
1. Adequate DC rail voltage – Check that the minimum DC input  
voltage does not fall below 70 VDC at maximum load, minimum  
input voltage.  
2. Correct Diode Selection – UF400x series diodes with reverse  
recovery time of 75 ns or better are recommended only for  
designs that operate in MDCM at an ambient of 70 °C or below.  
For designs operating in continuous conduction mode (CCM) and/  
or higher ambients, then a diode with a reverse recovery time of  
35 ns or better, such as the BYV26C, is recommended.  
3. Maximum drain current – Verify that the peak drain current is  
below the data sheet peak drain specification under worst-case  
conditions of highest line voltage, maximum overload (just prior  
to auto-restart) and highest ambient temperature.  
In a LinkSwitch-TN2 design using a buck or buck-boost converter  
topology, the SOURCE pin is a switching node. Oscilloscope measure-  
ments should therefore be made with probe grounded to a DC voltage,  
such as primary return or DC input rail, and not to the SOURCE pins.  
The power supply input must always be supplied from an isolated  
source when doing measurements (e.g. via an isolation transformer).
