HIP6004B
Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004B 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 HIP6004B 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 HIP6004B includes a fully TTL-
compatible 5-input digital-to-analog converter (DAC) that
adjusts the output voltage from 1.3V
DC
to 2.05V
DC
in
0.05V and from 2.1V
DC
to 3.5V
DC
in 0.1V increments
steps. The precision reference and voltage-mode regulator
hold the selected output voltage to within
±
1% over
temperature and line voltage variations.
The HIP6004B 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/
μ
s slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0% to 100%.
The HIP6004B 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
HIP6004B 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 HIP6004B monitors the current by
using the r
DS(ON)
of the upper MOSFET which eliminates
the need for a current sensing resistor.
