Description

The LP5553 is a System Power Management Interface (SPMI) compliant Energy Management Unit for reducing power consumption of low power hand held applications such as dual-core processors and DSPs.

The LP5553 contains 2 advanced, digitally controlled step-down DC/DC converters for supplying variable voltages to a SoC. 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-domain) in shutdown-mode.

The LP5553 implements 2 Non-Request Capable Slaves that are controlled via the SPMI. The LP5553 operates cooperatively with PowerWise ® AVS 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 look-up tables.

Reliability Metrics

Part NumberProcessEFR RejectEFR Sample SizePPMLTA RejectsLTA Device HoursFITSMTTF (Hours)

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
