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 can be easily downgraded to 3 phases by removing one phase. 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 L6714 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 mosfets. System Thermal Monitor is also provided allowing system protection from over-temperature conditions.
