SC174
inner layers to expand the heat sinking area.
On the bottom layer, the resistor network composed of
R3 and R4 determines the output voltage. C7 is the feed
forward capacitor which helps to stabilize the circuit. R6
in series with C9 is connected to the LX pin (through the
via) to the power ground. C8 is the coupling capacitor
which injects the ramp signal generated on C9 to the FB
pin of the SC174. R7 is the pull up resistor for the PGOOD
pin.
