Bypassing and Grounding
The LTC4440 requires proper bypassing on the V
CC
and
V
BOOST–TS
supplies due to its high speed switching (nano-
seconds) and large AC currents (Amperes). Careless
component placement and PCB trace routing may cause
excessive ringing and under/overshoot.
To obtain the optimum performance from the LTC4440:
A. Mount the bypass capacitors as close as possible
between the V
CC
and GND pins and the BOOST and TS
pins. The leads should be shortened as much as pos-
sible to reduce lead inductance.
B. Use a low inductance, low impedance ground plane to
reduce any ground drop and stray capacitance. Re-
member that the LTC4440 switches >2A peak currents
and any significant ground drop will degrade signal
integrity.

C. Plan the power/ground routing carefully. Know where
the large load switching current is coming from and
going to. Maintain separate ground return paths for the
input pin and the output power stage.
D.Keep the copper trace between the driver output pin and
the load short and wide.
E. When using the MS8E package, be sure to solder the
exposed pad on the back side of the LTC4440 package
to the board. Correctly soldered to a 2500mm
2
double-
sided 1oz copper board, the LTC4440 has a thermal
resistance of approximately 40
°
C/W. Failure to make
good thermal contact between the exposed back side
and the copper board will result in thermal resistances
far greater than 40
°
C/W.
