Description
L6714 implements a four phase step-down
controller with 90 phase-shift between each
phase with integrated high current drivers in a
compact 10mm x 10mm body package with
exposed pad.
The device embeds selectable DACs: the output
voltage ranges up to 1.60000V (both Intel VR10.x
and VR11 DAC) or up to 1.5500V (AMD 6Bit
DAC) managing D-VID with ±0.5% output voltage
accuracy over line and temperature variations.
Additional programmable offset can be added to
the reference voltage with a single external
resistor.
The controller assures fast protection against load
over current and under / over voltage (in this last
case also before UVLO). In case of over-current
the system works in Constant Current mode until
UVP.
Selectable current reading adds flexibility to the
design allowing current sense across inductor or
LS MOSFET.
System Thermal Monitor is also provided allowing
system protection from over-temperature
conditions.
