Buck Pulse-Width Modulator (PWM)
Controller and Output Voltage Monitor
The HIP6003 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
HIP6003 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 HIP6003 includes a 4-Input
Digital-to-Analog Converter (DAC) that adjusts the output
voltage from 2.0VDC to 3.5VDC in 0.1V increments. The
precision reference and voltage-mode regulator hold the
selected output voltage to within ±1% over temperature and
line voltage variations.
The HIP6003 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 HIP6003 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 HIP6003
protects against over-current conditions by inhibiting PWM
operation. Built-in over-voltage protection triggers an
external SCR to crowbar the input supply. The HIP6003
monitors the current by using the rDS(ON) of the upper
MOSFET which eliminates the need for a current sensing
resistor.
