NCP6121S52MNR2G Description

Short technical summary and product information.

The NCP6121S52MNR2G is a dual output three plus one phase buck controller from ON Semiconductor, optimized for Intel VR12 compatible CPUs. This device integrates true differential voltage sensing, differential inductor DCR current sensing, input voltage feed-forward, and adaptive voltage positioning for accurate power regulation in desktop applications.

The control system utilizes Dual-Edge pulse-width modulation (PWM) combined with DCR current sensing for rapid initial response to dynamic load events. It supports power saving phase shedding during light load operation and can auto-frequency scale while maintaining excellent transient performance. The controller features dual high-performance operational error amplifiers and patented Dynamic Reference Injection to simplify system compensation.

Key features include meeting Intel VR12 and IMVP7 specifications, current mode dual edge modulation, one digital soft start ramp for both rails, and accurate total summing current amplifier. It also incorporates DAC with droop feed-forward injection and dual high impedance differential voltage and total current sense amplifiers. The device uses "lossless" DCR current sensing for balancing and summed thermally compensated inductor current sensing for droop.

Packaged in a 52-pin QFN, the NCP6121S52MNR2G is suitable for surface mount applications. It meets Intel VR12 and IMVP7 specifications and is RoHS3 compliant.
