Introduction
provides feedback for droop compensation and over-current
Each generation of computer microprocessor brings
performance advances in computing power. Performance
improvements are made possible by advances in fabrication
technology that enable greater device density. Newer
processors are operating at lower voltages and higher clock
speeds both of which contribute to greater demands on the
protection. A ?ve-bit DAC provides a digital interface to
program the 1% accurate reference and a window
comparator toggles PGOOD if the output voltage is out of
range and acts to protect the load in case of over voltage.
For more detailed descriptions of the HIP6302 functionality,
refer to the HIP6302 Data Sheet [1].
microprocessor core voltage supply in terms of higher peak
The HIP6601A is a driver IC capable of delivering up to 2A of
currents and higher current-slew rates.
gate-charging current for rapidly switching both MOSFETs in
Intersil’s family of multi-phase DC-DC converter solutions
provide the ideal solution to supply the core-voltage needs of
present and future high-performance microprocessors.
a synchronous-recti?ed bridge. The HIP6601A accepts a
single logic input to control both upper and lower MOSFETs.
Adaptive shoot-through protection is provided on both
switching edges to provide optimal dead time, and bootstrap
