HIP6005
Buck Pulse-Width Modulator (PWM)
Controller and Output Voltage Monitor
The HIP6005 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
HIP6005 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 HIP6005 includes a 5-input digital-
to-analog converter (DAC) that adjusts the output voltage
from 2.1V
DC
to 3.5V
DC
in 0.1V increments and from 1.3V
DC
to 2.1V
DC
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 HIP6005 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 HIP6005 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 HIP6005
protects against over-current conditions by inhibiting PWM
operation. Built-in over-voltage protection triggers an
external SCR to crowbar the input supply. The HIP6005
monitors the current by using the r
DS(ON)
of the upper
MOSFET which eliminates the need for a current sensing
resistor.
