Size optimization design procedure
The evaluation board size is often one of the most important considerations during the
design procedure. There are ways to shrink the board size smaller than those shown in
Figure 3
The main size-limiting components of the board are the C4 capacitor, the R6, R7, and R10
resistors, the heat sink on the TRIAC, and the EMI filter.
Since it is not possible to optimize the evaluation board for these devices, the original design
uses the 16 A BTB16-600CW TRIAC, a heat sink for the output power of up to 1 kW, and an
input CLC filter (C7 = 470 nF, L1 = 0.1 mH, and C9 = 100 nF). In fact, users can design the
board with any EMI filter or even any heat sink for the TRIAC because there is enough
space to do so.
To minimize the size of the board:

If all of these points are taken into account, and the EMI filter and large power supply are not
required (small or no heat sink), the optimal design can achieve an evaluation board about
the size of 3 cm x 3 cm.
Resistors R1, R2, R3, R4, R5, and R8, capacitors C1, C2, C3, C5, and C6, diodes ZD1
and D1, or the ST7FLITE09 microcontroller need to be assembled in SMD version
The switch and button can be situated in another place (for example, a switch on the
wall)
