Layout Considerations
To take full tracking advantage of the switch response
time to an output fault condition, it is important to keep
all traces as short as possible and to maximize the
high-current trace dimensions to reduce the effect of
undesirable parasitic inductance. Place the MAX5918/
MAX5919 close to the card
’
s connector. Use a ground
plane to minimize impedance and inductance. Minimize
the current-sense resistor trace length (< 10mm), and
ensure accurate current sensing with Kelvin connections
(Figure 6).
When the output is short circuited, the voltage drop
across the external MOSFET becomes large. Hence,
the power dissipation across the switch increases, as
does the die temperature. An efficient way to achieve
good power dissipation on a surface-mount package is
to lay out two copper pads directly under the MOSFET
package on both sides of the board. Connect the two
pads to the ground plane through vias, and use
enlarged copper mounting pads on the top side of the
board (refer to the MAX5919 EV Kit).
