Package Description
Layout Guidelines
Good layout technique is required for systems that
combine sensitive amplifiers and switching
converters. Extra care must be taken to provide high
frequency decoupling and to avoid introducing noise
at sensitive nodes.
The capacitors for V
CC
decoupling and Soft Start
should provide low impedance paths to each pin
and be referenced to SGND close to the PI1004.
The connections from load V
SS
to SGND and the
load V
CC
to EAIP form an output voltage sense
pair and should be routed in parallel to avoid
noise pick-up. If the layout allows PI1004 return
current to flow through the load V
SS
to SGND
connection, trace resistance must be considered
to avoid an excessive offset voltage within the trace.
The PI1004 EA integrator capacitor should be
routed in a short loop to minimize noise pick-up.
R
G
and R
OFFSET
should be tied to SGND near the
PI1004 to avoid noise pickup.
