Figure 19 Schematic for recommended PCB layout
General guideline for PCB layout design using F3 CoolSET (refer to Figure 19):
1. “Star Ground “at bulk capacitor ground, C11:
Guideline for PCB layout design when >3KV lightning surge test applied (refer to Figure 19):
1. Add spark gap
Version 2.0
2. High voltage traces clearance:
3. Filter capacitor close to the controller ground:
a. Spark Gap 3 and Spark Gap 4, input common mode choke, L1:
a. 400V traces (positive rail of bulk capacitor C11) to nearby trace: > 2.0mm
b. 600V traces (drain voltage of CoolSET IC11) to nearby trace: > 2.5mm
a. DC ground of the primary auxiliary winding in power transformer, TR1, and ground of C16 and Z11.
b. DC ground of the current sense resistor, R12
c. DC ground of the CoolSET device, GND pin of IC11; the signal grounds from C13, C14, C15 and collector of
d. DC ground from bridge rectifier, BR1
e. DC ground from the bridging Y-capacitor, C4
High voltage traces should keep enough spacing to the nearby traces. Otherwise, arcing would incur.
Spark gap is a pair of saw-tooth like copper plate facing each other which can discharge the accumulated
Gap separation is around 1.5mm (no safety concern)
Spark Gap 1
charge during surge test through the sharp point of the saw-tooth plate.
Spark Gap 2
separately in one point. It can reduce the switching noise going into the sensitive pins of the CoolSET device
effectively. The primary DC grounds include the followings.
Filter capacitors, C13, C14 and C15 should be placed as close to the controller ground and the controller pin
as possible so as to reduce the switching noise coupled into the controller.
“Star Ground “means all primary DC grounds should be connected to the ground of bulk capacitor C11
IC12 should be connected to the GND pin of IC11 and then “star “connect to the bulk capacitor ground.
