HIP6004E
Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004E 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 HIP6004E 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 HIP6004E includes a 5-input digital-
to-analog converter (DAC) that adjusts the output voltage
from 1.05VDC to 1.825VDC 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 HIP6004E 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 HIP6004E 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 HIP6004E
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 HIP6004E 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 products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish, which
is 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-020B.
