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.
