Note 1:
Corresponds to 512 DPWM cycles or 65536 MODE
cycles.
Note 2:
When the buck switch is shorted, V
CTFB
goes high
causing V
CCV
to go below the fault detection threshold.
Note 3:
Corresponds to 64 DPWM cycles or 8192 MODE cycles.
Note 4:
The MODE pin thresholds are only valid while the part is
operating. In shutdown, V
REF
= 0 and the part only
differentiates between SMB mode and ADC mode. In
shutdown with ADC mode selected, the CRF/SDA and
CTL/SCL pins are at high impedance and will not cause
extra supply current when their voltages are not at
GND or VL.
