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.

Combined use of DCR and RDS(on) current

sensing assures precision in voltage positioning

and safe current sharing and OCP per each

phase.
