L6701

L6701 3 Phase Controller for VR10, VR9 and K8 CPUs Features ■ MULTI-DAC: VR9, VR10 AND K8 DAC SELECTABLE THROUGH SINGLE PIN 0.7% OUTPUT VOLTAGE ACCURACY ADJUSTABLE REFERENCE OFFSET HIGH CURRENT INTEGRATED DRIVERS DYNAMIC VID MANAGEMENT ACCURATE FULLY-DIFFERENTIAL LOADLINE CURRENT-SENSE ACROSS MAIN INDUCTORS MAKES BOM INDEPENDENT ON THE LAYOUT PRECISE CURRENT-SHARING AND OCP ACROSS LS MOSFETS CONSTANT OVER-CURRENT PROTECTION FEEDBACK DISCONNECTION PROTECTION PRELIMINARY OV PROTECTION OSCILLATOR INTERNALLY FIXED AT 100kHz (300kHz RIPPLE) EXT ADJUSTABLE SS_END / PGOOD SIGNAL INTEGRATED REMOTE-SENSE BUFFER PWSSO36 PACKAGE WITH EXPOSED PAD PowerSSO-36 ■ ■ ■ ■ ■ Description L6701 is an extremely simple, low-cost solution to implement a three phase step-down controller with integrated high-current drivers in a compact PowerSSO-36 package with exposed pad. The device embeds three selectable DACs: with a single pin it is possible to program the device to work in compatibility with VR9, VR10 or K8 applications managing D-VID with ±0.7% output voltage accuracy over line and temperature variations. Additional programmable offset can be added to the reference voltage with a single external resistor. Fast protection against load over current let the system works in Constant Current mode until UVP. Preliminary OVP allows full load protection in case of startup with failed HS. Furthermore, feedback disconnection prevents from damaging the load in case of misconnections in the system board...
