3,4 PHASE CONTROLLER
Data Brief
TQFP64 (Exposed Pad)
Description
L6713, L6714 implement a three/four phase
stepdown controller with 120º/90º phase-shift
between each phase with integrated high current
drivers in a compact 10x10mm body package with
exposed pad. Pin-to-pin compatibility allows
system scalability: a 4 phase application c an be
easily downgraded to 3 phases by removing one
phase. The device em beds selectable DACs: the
output voltage ranges up to 1.60 000V (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 ov er 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
mosfets. System Thermal Monitor is also provided
allowing system protection from over-temperature
conditions.
