HIP6005B
Buck Pulse-Width Modulator (PWM)
Controller and Output Voltage Monitor
The HIP6005B provides complete control and protection for
a DC-DC converter optimized for high-performance
microprocessor applications. It is designed to drive an
N-Channel MOSFET in a standard buck topology. The
HIP6005B 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 HIP6005B 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 increments and from 2.1V
DC
to 3.5V
DC
in 0.1V steps.
The precision reference and voltage-mode regulator hold the
selected output voltage to within
±
1% over temperature and
line voltage variations.
The HIP6005B 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 HIP6005B 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 HIP6005B
protects against over-current and over-voltage conditions by
inhibiting PWM operation. Additional built-in over-voltage
protection triggers an external SCR to crowbar the input
supply. The HIP6005B monitors the current by using the
r
DS(ON)
of the upper MOSFET which eliminates the need for
a current sensing resistor.
