Abstract:
A high voltage (HV) converter implemented on a printed circuit board (PCB) includes a double diffused metal oxide semiconductor (DMOS) package comprising a lead frame and a main DMOS chip. The lead frame includes a gate section electrically connected to a gate electrode of the main DMOS chip, a source section electrically connected to a source electrode of the main DMOS chip and a drain section electrically connected to a drain electrode of the main DMOS chip. The PCB layout includes a large area source copper pad attached to and overlapping the source section of the DMOS package to facilitate cooling and a small area drain copper pad attached to and overlapping the drain section of the DMOS package to reduce electromagnetic interference (EMI) noise.

Claim (Index 16):
A high voltage converter implemented on a printed circuit board (PCB) comprising:\n a transformer having a primary winding and a secondary winding; a DMOS package comprising a main switch having a source electrode connected to a source lead and a drain electrode connected to a drain lead; and a resistor having a first end and a second end; the second end of the resistor being connected to a ground; wherein the drain lead is attached to a drain copper pad on the PCB so that the drain electrode of the main switch is connected to a first end of the primary winding of the transformer; wherein the source lead is attached to a source copper pad on the PCB so that the source electrode of the main switch is connected to the first end of the resistor; and wherein an area of the source lead overlapping the source copper pad on the PCB is substantially larger than an area of the drain lead overlapping the drain copper pad on the PCB.
