For an equation for the ripple current see the section under
component guidelines titled ‘Output Inductor Selection.’
A small ceramic capacitor should be placed in parallel with
R
OCSET
to smooth the voltage across R
OCSET
in the pres-
ence of switching noise on the input voltage.
Output Voltage Program
The output voltage of a RC5054A converter is programmed
to discrete levels between 1.3V
DC
and 3.5V
DC
. The voltage
identification (VID) pins program an internal voltage refer-
ence (DACOUT) with a 5-bit digital-to-analog converter
(DAC). The level of DACOUT also sets the PGOOD and
OVP thresholds. Table 1 specifies the DACOUT voltage for
the 32 combinations of open or short connections on the VID
pins. The output voltage should not be adjusted while the
converter is delivering power. Remove input power before
changing the output voltage. Adjusting the output voltage
during operation could toggle the PGOOD signal and exer-
cise the overvoltage protection.
Grounding any combination of the VID pins increases the
DACOUT voltage.
