• Manufacturer: Analog Technology, Inc.

OUTLINE DIMENSIONS AND MOUNTING
The controller comes in only one package: through hole
mount. It is often called DIP (Dual Inline package) or D
(short for DIP) package and has a part number: CWD-01-
V2-D. Dimensions of the DIP package controller are
shown in Figure 6.
Figure 7 shows the foot-print which is seen from the end
side of the PCB.
Figure 8 shows the foot-print which is seen from the top
side of the PCB, therefore, it is a “see through” view.
“Tent” (i.e. cover the entire via by the solder mask
layer) all the vias under the controller, otherwise, the
vias can be shorted by the bottom plate of the controller
which is internally connected the ground.

See Figure 8 and 9, it is recommended to use large
copper fills for VPS, PGND, and the LDA pins, and
other pins if possible, to decrease the thermal resistance
between the module and the supporting PCB, to lower
the module temperature.

bottom side of the PCB.
