Description
Buck And Synchronous-rectifier Pwm Controller And Output Voltage Monitor
Manufacturer
Intersil Corporation
Datasheet
Buck and Synchronous-Rectifier (PWM)
Controller and Output Voltage Monitor
The HIP6004E 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 HIP6004E 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 HIP6004E includes a 5-input digital-
to-analog converter (DAC) that adjusts the output voltage
from 1.05V
precision reference and voltage-mode regulator hold the
selected output voltage to within ±1% over temperature and
line voltage variations.
The HIP6004E 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/µs slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0% to 100%.
The HIP6004E 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 HIP6004E
protects against over-current and overvoltage conditions by
inhibiting PWM operation. Additional built-in overvoltage
protection triggers an external SCR to crowbar the input
supply. The HIP6004E monitors the current by using the
r
a current sensing resistor.
