GROUNDING CONSIDERATIONS
ground (SGND), power ground (PGND) and digital ground
(DGND). SGND and PGND are the ground paths for the
SA305 while the DGND is for the MCU and related circuitry.
These grounds need to be connected on the board by putting
a jumper between SGND and DGND and another between
PGND and DGND. These jumpers are located in the center
of the board on the right of the SA305. Do not connect the
grounds at any other points to avoid ground loops and un-
wanted voltage drops.

P is the power dissipated
V is the VS supply voltage
C is the snubber capacitor value (15nF)
FSW is the switching frequency.
The EVAL49 has three separate ground paths for signal
DB62) are recommended for use as external flyback diodes
because of superior reverse recovery characteristics. Please
note that in the DB62, jumpers are needed in order to con-
nect the external schottky diodes (see EVAL49 layout).
R19 and C10 in EVAL49 schematic) can provide noise
immunity especially in high load current scenarios. A 100
V 4.7nF capacitor in series with a 50 ohm 5W resistor
(provided with kit) is recommended for the snubber to be
connected between each output and PGND.
