LT3782
APPLICATIONS INFORMATION
For best electrical performance, the LT3782 circuit should
be laid out as follows:
Place all power components in a tight area. This will
minimize the size of high current loops. Orient the input
and output capacitors and current sense resistors in a way
that minimizes the distance between the pads connected
to ground plane.
Use a local via to ground plane for all pads that connect to
ground. Use multiple vias for power components.
Connect the current sense inputs of LT3782 directly to the
current sense resistor pads. Connect the current sense
traces on the opposite sides of pads from the traces
carrying the MOSFETs source currents to ground. This
technique is referred to as Kelvin sensing.
Place the LT3782 and associated components tightly to-
gether and next to the section with power components.
