MagI³C Power Module
VDRM - Variable Step Down Regulator Module
DESIGN FLOW
Provide the single point ground connection from AGND pin 4 to the GND terminal of the output capacitor. This is the
point of lowest noise.
3: Minimize trace length to the FB pin.
The feedback resistors, R
FBT
and R
FBB
, and the feed forward capacitor C
FF
, should be located close to the FB pin.
Since the FB node is high impedance, maintain the copper area as small as possible. The traces from R
FBT
, R
FBB
,
and C
FF
should be routed away from the body of the MagI³C power module to minimize noise pickup.
