Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004 provides complete control and protection for a
DC-DC converter optimized for high-performance
microprocessor applications. It is designed to drive two
N-Channel MOSFETs in a synchronous-rectified buck
topology. The HIP6004 integrates all of the control, output
adjustment, monitoring and protection functions into a single
package.
The output voltage of the converter is easily adjusted and
precisely regulated. The HIP6004 includes a 5-input
digital-to-analog converter (DAC) that adjusts the output
voltage from 2.1VDC to 3.5VDC in 0.1V increments and from
1.3VDC to 2.1VDC in 0.05V steps. The precision reference
and voltage-mode regulator hold the selected output voltage
to within ±1% over temperature and line voltage variations.
The HIP6004 provides simple, single feedback loop,
voltage-mode control with fast transient response. It includes
a 200kHz free-running triangle-wave oscillator that is
adjustable from below 50kHz to over 1MHz. The error
amplifier features a 15MHz gain-bandwidth product and
6V/μs slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0% to 100%.
The HIP6004 monitors the output voltage with a window
comparator that tracks the DAC output and issues a Power
Good signal when the output is within ±10%. The HIP6004
protects against over-current conditions by inhibiting PWM
operation. Built-in over-voltage protection triggers an
external SCR to crowbar the input supply. The HIP6004
monitors the current by using the rDS(ON) of the upper
MOSFET which eliminates the need for a current sensing
resistor.

referenced to VIN) exceeds the voltage across ROCSET, the
over-current function initiates a soft-start sequence. The soft-
start function discharges CSS with a 10μA current sink and
inhibits PWM operation. The soft-start function recharges CSS,
and PWM operation resumes with the error amplifier clamped
to the SS voltage. Should an overload occur while recharging
CSS, the soft start function inhibits PWM operation while fully
charging CSS 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 CSS charging interval
and causes an over-current trip. The converter dissipates very
little power with this method. The measured input power for the
conditions of Figure 4 is 2.5W.
IPEAK = I--O-----C----S----rE--D--T--S----(--O-R----NO----)-C----S----E----T--
where IOCSET is the internal OCSET current source (200μA
typical). The OC trip point varies mainly due to the MOSFETs
rDS(ON) variations. To avoid over-current tripping in the
normal operating load range, find the ROCSET resistor from
the equation above with:
1. The maximum rDS(ON) at the highest junction temperature.
2. The minimum IOCSET from the specification table.
3.

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
ROCSET to smooth the voltage across ROCSET in the
presence of switching noise on the input voltage.
Output Voltage Program
The output voltage of a HIP6004 converter is programmed
to discrete levels between 1.3VDC and 3.5VDC . The
voltage identification (VID) pins program an internal voltage
reference (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 exercise the overvoltage protection.
The DAC function is a precision non-inverting summation
amplifier shown in Figure 5. The resistor values shown are
only approximations of the actual precision values used.
Grounding any combination of the VID pins increases the
DACOUT voltage. The ‘open’ circuit voltage on the VID pins
is the band gap reference voltage, 1.26V.
