HIP6005
Buck Pulse-Width Modulator (PWM) Controller and Output Voltage Monitor
FN4276
Rev.2.00
March 2000
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 2.1VDC to 3.5VDC in 0.1V increments and from 1.3VDC
to 2.1VDC 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/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 rDS(ON) of the upper
MOSFET which eliminates the need for a current sensing
resistor.
