DESCRIPTION
L6722 implements a three-phase step-down controller with 120º phase-shift between each phase with integrated high-current drivers in a compact VFQFPN36 package with exposed pad. L6722 manages output voltages down to 0.8V with ±1% output voltage accuracy over line and temperature variations. Additional programmable offset can be added to the reference voltage with a single external resistor in order to perform margining tests. In case of over-current the system works in Constant Current mode until UVP. Preliminary OVP allows full load protection in case of startup with failed HS.
