The NCP81530 and NCP81530R are dual rail, eight plus two phase buck solutions optimized for Intel®’s IMVP9.1 Rev0.9 and Rev0.95 CPU’s respectively. The multi−phase rail control system is based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing or smart power stage current sensing. These features provide an ultra−fast initial response to dynamic load events and reduced system cost. The NCP81530 has an ultra−low offset current monitor amplifier with programmable offset compensation for high accuracy current monitoring.
