HIP6004A
Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004A 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 HIP6004A 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 HIP6004A includes a fully TTL-
compatible 5-input digital-to-analog converter (DAC) that
adjusts the output voltage from 2.1VDC to 3.5VDC in 0.1V
increments and from 1.8VDC to 2.05VDC 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 HIP6004A 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/ms slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0% to 100%.
The HIP6004A 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 HIP6004A
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 HIP6004A monitors the current by using the
r
DS(ON)
of the upper MOSFET which eliminates the need for
a current sensing resistor.
