Dual, 3A, 2MHz Step-Down Regulator
For ratiometric tracking applications, connect REFIN to
the center of a voltage-divider from the output of regula-
tor 2 to GND (see Figure 3b). In this application, the EN_
inputs are connected to each other and driven as a sin-
gle enable input. Regulator 2 starts up with a normal soft-
start (C SS2 sets the time), and regulator 1 output
ratiometrically tracks the regulator 2 output voltage. The
voltage-divider resistors set the V OUT1 /V OUT2 ratio (see
the Setting the Output Voltage section). In Figure 3b,
V OUT1 regulates to half of V OUT2 . Note that a capaci-
tance of 1000pF should be connected to SS1 for stability.
Figure 3c shows the output sequencing application
using an external reference.
Sequencing is achieved by connecting EN2 to
PWRGD1. In this mode, regulator 2 starts once regulator
1 reaches regulation.
