Option 2: Dynamic Voltage Control Using SELPin
The output may be dynamically adjusted between
two output voltages by toggling the SEL logic pin.
Output voltages V
OUT(1)
and V
OUT(2)
correspond to
the two output references, FB1 and FB2. Pulling
the SEL logic pin high activates V
OUT(1)
, while
pulling the SEL logic pin low activates V
OUT(2)
.
In addition, the ratio of output voltages V
OUT(2)
/V
OUT(1)
is always less than 2.0, corresponding to a 2X (max-
imum) programmable range.
Option 3: Dynamic Voltage Control Using
S
2
Cwire Interface
The output can be dynamically adjusted by the host
controller to any of 16 pre-set output voltage levels
using the integrated S
2
Cwire interface. The
EN/SET pin serves as the S
2
Cwire interface input.
The SEL pin must be pulled low when using the
S
2
Cwire interface.
S
2
Cwire Serial Interface
AnalogicTech's S
2
Cwire serial interface is a propri-
etary high-speed single-wire interface. The S
2
Cwire
interface records rising edges of the EN/SET input
and decodes into 16 different states. Each state
corresponds to a voltage setting on the FB2 pin, as
shown in Table 6.
S
2
Cwire Output Voltage Programming
The AAT1210 is programmed through the S
2
Cwire
interface according to Table 6. The rising clock
edges received through the EN/SET pin determine
the feedback reference and output voltage set-
point. Upon power-up with the SEL pin low and
prior to S
2
Cwire programming, the default feedback
reference voltage is set to 0.6V.
