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.

Keep the 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.
