VOLTAGE REGULATOR MODULE
BY (VRM)
ED
The RCB010 from Raytheon
IV Electronics is a programmable DC-DC Voltage Regulator Module designed
H
to deliver the selectable
processor core voltage required by the PowerPC processor. The RCB010 takes
C
R
full advantage of
a Raytheon programmable DC-DC controller IC. This IC integrates a 5-bit DAC for
A
automatic output programmability without the need for external precision resistors. The RCB010 provides
an extremely well regulated selectable output voltage from 1.3V to 3.5V. Output voltage selection is
accomplished through a 5-bit interface between the processor interposer and the module connector.
The VID selections are done on the interposer. Do not populate J45,J46, J47, J55 and J56 unless you are
instructed by a Motorola field application engineer.
