VRD Design Guide Addendum
5 Output Protection
These are features built into the VRD to prevent damage to itself, the processor, or other system
components.
5.1 Over-Voltage Protection (OVP) (PROPOSED)
An OVP circuit should monitor the output for an over-voltage condition. If the output is more
than 200mV above the maximum VID level, the VRD should shut off the Vcc supply to the
processor.
5.2 Over-Current Protection (OCP) (PROPOSED)
The VRD should be capable of withstanding a continuous, abnormally low resistance on the
output without overstressing the voltage regulator. Output current under this condition should be
limited to avoid component damage and violation of the VRD thermal specifications (see Section
2.5).
