Buck Pulse-Width Modulator (PWM)
Controller
The HIP6007 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
HIP6007 integrates all of the control, output adjustment,
monitoring and protection functions into a single package.
The output voltage of the converter can be precisely
regulated to as low as 1.27V, with a maximum tolerance of
±1% over temperature and line voltage variations.
The HIP6007 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
ampliï¬er 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 HIP6007 protects against over-current conditions by
inhibiting PWM operation. The HIP6007 monitors the current
by using the rDS(ON) of the upper MOSFET which eliminates
the need for a current sensing resistor.
