APPLICATION INFORMATION
layout
Another benefit of a separate controller and pass element is that the heat dissipated in the external NMOS can
be well isolated from the controller, which has very low power dissipation. Both of these factors allow the
bandgap reference and control circuitry to operate over a more stable temperature range, resulting in very good
accuracy over full-load conditions. The LFC789D25 should be placed as close as possible to the external pass
element because short PCB traces allow minimal EMI coupling to both the drive and sense lines.
For best accuracy, connect the SEN pins as close to the load as possible, not to the source of the NMOS. Also,
place the SEN trace in the same direction and plane as the power trace that connects the source of the NMOS
to the load. Also, it is good practice to keep the load current return path as far as possible from the SEN trace.
Place the 0.1-
μ
F bypass capacitor as close as possible to the V
CC
pin and connect it directly to the ground plane.
The GND pin of the LFC789D25 should be connected to the ground plane.
