The LP5552 contains 2 advanced, digitally controlled switching regulators for supplying variable voltages to a SoC or processor. The device also incorporates 5 programmable low-dropout, low-noise linear regulators for powering I/O, peripheral logic blocks, auxiliary system functions, and maintaining memory retention (dual-domains) in shutdown-mode. The device is controlled via the high-speed serial PWI 2.0 open-standard interface. The LP5552 operates cooperatively with PowerWise technology-compatible processors to optimize supply voltages adaptively (AVS - Adaptive Voltage Scaling) over process and temperature variations. It also supports dynamic voltage scaling (DVS) using frequency/voltage pairs from pre-characterized lookup tables.
