area should be provided at the anode and cathode terminals  
of the diode for heat sinking. A larger area is preferred at the  
quiet cathode terminal. A large anode area can increase high  
frequency radiated EMI.

edge current spike event is below ILIMIT(MIN) at the end of the  
tLEB(MIN). Under all conditions, the maximum drain current  
should be below the specied absolute maximum ratings.  
3. Thermal Check – At specied maximum output power,  
minimuminputvoltageandmaximumambienttemperature,  
verify that the temperature specications are not exceeded  
for LinkSwitch-XT, transformer, output diode and output  
capacitors. Enough thermal margin should be allowed for  
part-to-part variation of the RDS(ON) of LinkSwitch-XT as  
speciedinthedatasheet.Underlowline,maximumpower,  
a maximum LinkSwitch-XT SOURCE pin temperature of  
105 °C is recommended to allow for these variations.  
Quick Design Checklist  
As with any power supply design, all LinkSwitch-XT designs  
should be veried on the bench to make sure that component  
specicationsarenotexceededunderworst-caseconditions.The  
following minimum set of tests is strongly recommended:  
1. Maximum drain voltage – Verify that VDS does not exceed  
650Vatthehighestinputvoltageandpeak(overload)output  
power. The 50 V margin to the 700 V BVDSS specication  
gives margin for design variation, especially in Clampless  
designs.  
2. Maximumdraincurrent–Atmaximumambienttemperature,  
maximum input voltage and peak output (overload) power,  
verify drain current waveforms for any signs of transformer
