There are numerous ways in which a designer might modify
the ISL6532AEVAL1 evaluation board for differing
requirements. Some of the changes which are possible
include:
1.230V
1.480V
V AGP
50mV/DIV
V DDQ Load
10A/DIV
V TT Load
2A/DIV
200 μ s/DIV

? The input and output inductors, L1 and L2
? The input and output capacitance for any of the three
regulators.
? The overcurrent trip point, programmed through the
OCSET resistor, R7
? By changing the value of C19, the soft start profile of the
V TT rail, when transitioning from Sleep to Active State
? All MOSFET footprints on the evaluation board allow for
either SO8 or PowerPak packaged MOSFETs to be
utilized
? The 3.3VSBY LDO, Ux1, may be circumvented by
shorting pins 2 and 3 together. This will provide the V DDQ
standby LDO with 5V while in Sleep state, which allows
the load to be increased by 100mA.

Conclusion
The ISL6532AEVAL1 is a versatile platform that allows
designers to gain a full understanding of the functionality of
the ISL6532A in a DDR Memory System. The board is also
flexible enough to allow the designer to modify the board for
differing requirements.

Efficiency
Figure 11 shows the efficiency of the VDDQ regulator while
in Active (S0) State. As the other regulated outputs are all
derived through linear regulation, their efficiencies are not
shown.
