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 HIP6004B 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.
‘11111’ VID pin combination resulting in a 0V output setting
activates the Power-On Reset function and disables the gate
drives circuitry. For this specific VID combination, though,
PGOOD asserts a high level. This unusual behavior has been
implemented in order to allow for operation in dual-
microprocessor systems where AND-ing of the PGOOD
signals from two individual power converters is implemented.
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.
