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
presence of switching noise on the input voltage.
Output Voltage Program
The output voltage of a HIP6005A converter is programmed
to discrete levels between 1.8V
DC
and 3.5V
DC
. The voltage
identification (VID) pins program an internal voltage
reference (DACOUT) with a TTL-compatible 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 different combinations of
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 exercise the overvoltage protection.
All VID pin combinations resulting in a 0V output setting
activate the Power-On Reset function, disable the gate drive
circuitry and output a 0 logic at PGOOD pin.
Application Guidelines
Layout Considerations
As in any high frequency switching converter, layout is very
important. Switching current from one power device to
another can generate voltage transients across the
impedances of the interconnecting bond wires and circuit
traces. These interconnecting impedances should be
minimized by using wide, short printed circuit traces. The
critical components should be located as close together as
possible using ground plane construction or single point
grounding.
