Primary Loop Area

rectiﬁer. This effectively ﬁlters the leakage inductance spike

and reduces the error that this would give when using fast

recovery time diodes. The use of a slow diode is a requirement

in Clampless designs.

The area of the primary loop that connects the input ﬁlter

capacitor, transformer primary and LinkSwitch-LP together

should be kept as small as possible.

Primary Clamp Circuit

Lin k S w it c h -LP Layout Considerations

An external clamp may be used to limit peak voltage on the

DRAIN pin at turn off. This can be achieved by using an RCD

clamp or a Zener (~200 V) and diode clamp across the primary

winding. In all cases, to minimize EMI, care should be taken

to minimize the circuit path from the clamp components to the

transformer and LinkSwitch-LP.

Layout

See Figure 6 for a recommended circuit board layout for

LinkSwitch-LP.

Single Point Grounding

Use a single point ground connection from the input ﬁlter

capacitor to the area of copper connected to the SOURCE

pins.

Thermal Considerations

The copper area underneath the LinkSwitch-LP acts not only as

a single point ground, but also as a heatsink. As it is connected

to the quiet source node, this area should be maximized for

good heat sinking of LinkSwitch-LP. The same applies to the

cathode of the output diode.
