Table 1 Continued - Voltage Identification (VID)
Slew Rate Programming Capacitor C
DAC
and Resistor R
DAC
VDAC sink current I
SINK
and source current I
SOURCE
are determined by R
ROSC,
and their value can be found using
the curve in this data sheet. The slew rate of VDAC down-slope SR
DOWN
can be programmed by the external
capacitor C
DAC
as defined in Equation (1) and shown in Figure1. Resistor R
DAC
is used to compensate VDAC
circuit and is determined by Equation (2). The slew rate of VDAC up-slope SR
UP
is proportional to the down-slope
slew rate SR
DOWN
and is given by Equation (3).
