Locate the feedback resistors in close proximity to the
LT3845 to minimize the length of the high impedance
VFB node.
The SENSE– and SENSE+ traces should be routed together
and kept as short as possible.
APPLICATIONS INFORMATION
The LT3845 packaging has been designed to efciently
remove heat from the IC via the Exposed Pad on the
backside of the package. The Exposed Pad is soldered to
a copper footprint on the PCB. This footprint should be
made as large as possible to reduce the thermal resistance
of the IC case to ambient air.
