Table 59. Register 0x3B—Light Load Mode Disable Settings

Bits

Bit Name

R/W

Description

Disable OUTAUX

R/W

Setting this bit means that OUTAUX is also disabled if the load current falls below the light load SR

disable threshold.

Disable OUTD

R/W

Setting this bit means that OUTD is also disabled if the load current falls below the light load SR

disable threshold.

Disable OUTC

R/W

Setting this bit means that OUTC is also disabled if the load current falls below the light load SR

disable threshold.

Disable OUTB

R/W

Setting this bit means that OUTB is also disabled if the load current falls below the light load SR

disable threshold.

Disable OUTA

R/W

Setting this bit means that OUTA is also disabled if the load current falls below the light load SR

disable threshold.

Light load SR

disable

R/W

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.
