Internal Multiplexers
The MAX8760 has a unique internal DAC input
multiplexer (MUXes) that selects one of three different
DAC code settings for different processor states
(Figure 3). On startup, the MAX8760 selects the DAC
code from the D0–D5 (SUS = GND) or S0, S1 (SUS = REF
or high) input decoders.
DAC Inputs (D0–D5)
During normal forced-PWM operation (SUS = GND), the
digital-to-analog converter (DAC) programs the output
voltage using the D0–D5 inputs. Do not leave D0–D5
unconnected. D0 –D5 can be changed while the
MAX8760 is active, initiating a transition to a new output
voltage level. Change D0–D5 together, avoiding greater
than 1μs skew between bits. Otherwise, incorrect DAC
readings can cause a partial transition to the wrong volt-
age level followed by the intended transition to the correct
voltage level, lengthening the overall transition time. The
available DAC codes and resulting output voltages are
compatible with AMD K9 voltage specifications (Table 4).
