The HIP6004D 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 HIP6004D 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 HIP6004D includes a fully TTL-
compatible 5-input digital-to-analog converter (DAC) that
adjusts the output voltage from 1.1VDC to 1.85VDC in 25mV
increments steps. The precision reference and voltage-
mode regulator hold the selected output voltage to within
1% over temperature and line voltage variations.
The HIP6004D 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/s slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0% to 100%.
The HIP6004D 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 HIP6004D
protects against over-current and overvoltage conditions by
inhibiting PWM operation. Additional built-in overvoltage
protection triggers an external SCR to crowbar the input
supply. The HIP6004D monitors the current by using the
rDS(ON) of the upper MOSFET which eliminates the need for
a current sensing resistor.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb
and Pb-free soldering operations. Intersil Pb-free products are MSL classified
at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
