Place the small-signal components away from high
frequency switching nodes. This allows the use of a
pseudo-Kelvin connection for the signal ground, where
high di/dt gate driver currents flow out of the IC ground
pin in one direction (to the bottom plate of the V
coupling capacitor) and small-signal currents flow in the
other direction.
Keep the trace from the feedback divider tap to the FB pin
short to preclude inadvertent pickup.
APPLICATIONS INFORMATION
CC
de-
For applications with multiple switching power converters
connected to the same input supply, make sure that the
input filter capacitor for the LT3825 is not shared with
other converters. AC input current from another converter
could cause substantial input voltage ripple and this could
interfere with the LT3825 operation. A few inches of PC
trace or wire (L ≅ 100nH) between the C
and the actual source V
sharing problems.
