product overview ncp6151: vr12 2-, 3-, 4-phase cpu controller + 1-phase gpu controller for complete documentation, see the data sheet product description ncp6151/ncp6151a dual output four plus one phase buck solution is optimized for intel vr12 compatible cpus. the controller combines true differential voltage sensing, differential inductor dcr current sensing, input voltage feed-forward, and adaptive voltage positioning to provide accurately regulated power for both desktop and notebook applications. the control system is based on dual-edge pulse width modulation (pwm) combined with dcr current sensing providing the fastest initial response to dynamic load events and reduced system cost. it also sheds to single phase during light load operation and can auto frequency scale in light load while maintaining excellent transient performance. features ? meets intel vr12/imvp7 specifications ? current mode dual edge modulation for fastest initial response to transient loading ? dual high performance operational error amplifier ? one digital soft start ramp for both rails applications ? desktop and notebook processors part electrical specifications product compliance status topology phases control mode vcc min (v) vcc max (v) fsw typ (khz) tres typ (ns) package type ncp6151ad52mnr2 g pb-free halide free active qfn-52 ncp6151d52mnr2g pb-free halide free active qfn-52 NCP6151S52MNR2G pb-free halide free active qfn-52 for more information please contact your local sales support at www.onsemi.com created on: 6/16/2013
