LT3845
APPLICATIONS INFORMATION
Locate the feedback resistors in close proximity to the
LT3845 to minimize the length of the high impedance
V FB node.
The SENSE – and SENSE + traces should be routed together
and kept as short as possible.
The LT3845 TSSOP package has been designed to ef-
?ciently 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.
