PCB Layout of a 2.1 W, 6 V, 350 mA Charger.
Output Diode (D O )
For best performance, the area of the loop connecting the
secondary winding, the output diode (D O ) and the output filter
capacitor (C O ) should be minimized. In addition, sufficient
copper area should be provided at the anode and cathode
terminals of the diode for heat sinking. A larger area is preferred
at the electrically “quiet” cathode terminal. A large anode area
can increase high frequency conducted and radiated EMI.
Resistor R S and C S represent the secondary side RC snubber.
Quick Design Checklist
As with any power supply design, all LinkZero-AX designs
should be verified on the bench to make sure that component
specifications are not exceeded under worst-case conditions.
The following minimum set of tests is strongly recommended:
1. Maximum drain voltage – Verify that V DS does not exceed
660 V at the highest input voltage and peak (overload) output
power. This margin to the 700 V BV DSS specification gives
margin for design variation, especially in clampless designs.

Rev. B 11/12
2. Maximum drain current – At maximum ambient temperature,
maximum input voltage and peak output (overload) power,
verify drain current waveforms for any signs of transformer
saturation and excessive leading-edge current spikes at
start-up. Repeat under steady state conditions and verify
that the leading-edge current spike event is below I LIMIT(MIN) at
the end of the t LEB(MIN) . Under all conditions, the maximum
drain current should be below the specified absolute
maximum ratings.
3. Thermal check – At specified maximum output power,
minimum input voltage and maximum ambient temperature,
verify that the temperature specifications are not exceeded
for LinkZero-AX, transformer, output diode and output
capacitors. Enough thermal margin should be allowed for
part-to-part variation of the R DS(ON) of LinkZero-AX as specified
in the data sheet. Under low line and maximum power, maxi-
mum LinkZero-AX source pin temperature of 100 °C is
recommended to allow for these variations.
