Single Output Controller with SVID Interface for Desktop and Notebook CPU Applications NCP81283 The NCP81283 (6 phase) is a single rail, six−output buck solution optimized for Intel®’s IMVP9 CPUs. The multi−phase rail control system is based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing. This provides an ultra−fast initial response to dynamic load events and reduced system cost. The NCP81283 has an ultra−low offset current monitor amplifier with programmable offset compensation for high accuracy current monitoring. Multi−Phase Features • Vin range 4.
