HIP6015
Buck Pulse-Width Modulator (PWM)
Controller and Output Voltage Monitor
The HIP6015 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
HIP6015 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 HIP6015 includes a fully
TTL-compatible 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 1.8V
DC
to 2.05V
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 HIP6015 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 HIP6015 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 HIP6015
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 HIP6015 monitors the current by using the
r
DS(ON)
of the upper MOSFET which eliminates the need for
a current sensing resistor.
