MagI³C Power Module
VDRM - Variable Step Down Regulator Module
3: Minimize trace length to high impedance pins
The feedback resistor, R
SET
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
SET
should be routed away from the body of the MagI³C power module
to minimize noise pickup.
Place R
RT
, and C
SS
as close as possible to their respective pins.

4: Make input and output terminal connections as wide as possible
This reduces any voltage drops on the input or output of the converter and maximizes efficiency.
