ISL95820EVAL1Z Evaluation Board User Guide
Hardware Description
Interface Connections
The ISL95820EVAL1Z evaluation board demonstrates the
performance of the ISL95820 4-phase voltage regulator for
Intel VR12.5 and VR12.6 CPUs. The ISL95820 features
Intersil's Robust Ripple Regulator R3 Technology™. An
on-board dynamic-load generator is included for evaluating the
transient-load response. It applies a 300µs pulse of
approximately 0.05/0.1load across VCORE and PGND.

Application Note 1902
The ISL95820 evaluation board features an Intel processor
socket (reference designator U2), intended for the installation of
an Intel VRTT (Voltage Regulator Test Tool) Interposer. This device
is required for VR platform validation, to establish compliance
with various Intel platform performance specifications.

FIGURE 1. TEST SET-UP
• Apply VIN (recommend +12V) to J5/J6 and apply +5V to
TP29/TP30. LED D1 should be red when S3 is off. Then flip on
S3 to start up controller. The following facts need to be
established for a good board:
- LED D1 turns green.
- Voltage meter measurement on TP35/TP36 shows ~1.70V.
FIGURE 2. SVID/SMBus EMULATOR SOFTWARE
Operation of the PMBus interface requires an Intersil-supplied
interface module, as shown in Figure 3. See the ISL95820
datasheet for information about the PMBus interface.
