HIP6004
Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004 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 HIP6004 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 HIP6004 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 HIP6004 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 HIP6004 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 HIP6004
protects against over-current conditions by inhibiting PWM
operation. Built-in over-voltage protection triggers an
external SCR to crowbar the input supply. The HIP6004
monitors the current by using the r
DS(ON)
of the upper
MOSFET which eliminates the need for a current sensing
resistor.
