Layout Considerations
The following advice should be considered when laying
out a printed circuit board for the LTC4355.
The inputs to the servo amplifiers, IN1, IN2, and OUT
should be connected as closely as possible to the
MOSFETs’ terminals for good accuracy.
K
eep th
e traces to the MOSFETs wide and short. The PCB
traces associated with the power path through the MOS-
FETs should have low resistance (see Figure 3).
For the DFN package, pin spacing may be a concern at
voltages greater than 30V. Check creepage and clearance
guidelines to determine if this is an issue. Use no-clean
solder to minimize PCB contamination.
