Controller IC Chip - NCP6121 NCP6121MNR2G Chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0791)
The NCP6121 dual output three plus one phase buck solution isoptimized for Intel VR12 compatible CPUs. The controller combinestrue differential voltage sensing, differential inductor DCR currentsensing, input voltage feed−forward, and adaptive voltage positioningto provide accurately regulated power for Desktop applications. Thecontrol system is based on Dual−Edge pulse−width modulation(PWM) combined with DCR current sensing providing the fastestinitial response to dynamic load events and reduced system cost. Italso sheds to single phase during light load operation and can autofrequency scale in light load while maintaining excellent transientperformance.Dual high performance operational error amplifiers are provided tosimplify compensation of the system. Patented Dynamic ReferenceInjection further simplifies loop compensation by eliminating the needto compromise between closed−loop transient response and DynamicVID performance. Patented Total Current Summing provides highlyaccurate current monitoring for droop and digital current monitoring.
