Description
Setting this bit means that OUTAUX is also disabled if the load current falls below the light load SR
disable threshold.
Setting this bit means that OUTD is also disabled if the load current falls below the light load SR
disable threshold.
Setting this bit means that OUTC is also disabled if the load current falls below the light load SR
disable threshold.
Setting this bit means that OUTB is also disabled if the load current falls below the light load SR
disable threshold.
Setting this bit means that OUTA is also disabled if the load current falls below the light load SR
disable threshold.
These bits set the load current limit on the CS2 ADC below which the synchronous rectifier outputs
(SR1 and SR2) are disabled. This value also determines the point at which the power supply goes into
light load mode and the light load mode filter is used. This value is programmable as a percentage of
the CS2 ADC full scale (either 60 mV or 120 mV). The hysteresis and the averaging speed are programmable
in Register 0x7D.

Description
This register contains the manufacturer’s silicon revision code for the device. This value is used by the
manufacturer for tracking purposes.
Description
This register contains the manufacturer’s ID code for the device. It is used by the manufacturer for test
purposes and should not be read from in normal operation. This value is hardwired to 0x41 to
represent the Analog Devices ID code.
