APPLICATIONS INFORMATION

PC Board Layout Guidance

When laying out the printed circuit board, the

following checklist should be used to ensure proper

operation of the IC.

1) Arrange the power components to reduce the

and the Schottky diode.

power GND with vias or short and wide path.

3) Use “Kelvin” or “4-wire” connection techniques

from the sense resistor pads directly to the CSP

and CSN1, CSN2 pins.

4) Use copper plane and thermal vias for GND for

best heat dissipation and noise immunity.

GND. It should be isolated away from the rest

of circuit for good EMI and low noise operation.
