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 L6701 embeds three selectable DACs: with a single pin L6701 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.

Combined use of DCR and RDS(on) current sensing assures precision in voltage positioning and safe current sharing and OCP per each phase.
