typical). The OC trip point varies mainly due to the
MOSFET’s r DS(ON) variations. To avoid overcurrent tripping
in the normal operating load range, find the R OCSET resistor
from the equation above with:

FIGURE 4. OVER-CURRENT OPERATION
The overcurrent function cycles the soft-start function in a
hiccup mode to provide fault protection. A resistor (R OCSET )
programs the overcurrent trip level. An internal 200 μ A current
sink develops a voltage across R OCSET that is referenced to
V IN . When the voltage across the upper MOSFET (also
referenced to V IN ) exceeds the voltage across R OCSET , the
overcurrent function initiates a soft-start sequence. The soft-
start function discharges C SS with a 10 μ A current sink and
inhibits PWM operation. The soft-start function recharges
C SS , and PWM operation resumes with the error amplifier
clamped to the SS voltage. Should an overload occur while
recharging C SS , the soft-start function inhibits PWM operation
while fully charging C SS to 4V to complete its cycle. Figure 4
shows this operation with an overload condition. Note that the
inductor current increases to over 15A during the C SS
charging interval and causes an overcurrent trip. The
converter dissipates very little power with this method. The
measured input power for the conditions of Figure 4 is 2.5W.
The overcurrent function will trip at a peak inductor current
(I PEAK) determined by:
I OCSET x R OCSET
I PEAK = -----------------------------------------------------
2. The minimum I OCSET from the specification table.
3. Determine I PEAK for I PEAK > I OUT ( MAX ) + ( ? I ) ? 2 ,
where ? I is the output inductor ripple current.
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 HIP6004E converter is programmed to
discreet levels between 1.05V DC and 1.825V 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.
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.
