Find architecture guidance for six power functions: DC-DC conversion, linear regulation, multi-rail management, battery charging, protection and smart distribution. Each page explains design priorities, operating limits to define and related application contexts.
DC-DC Power Conversion
Architecture guidance for converting one DC supply to the rails your system needs. Explore buck, boost and buck-boost choices, the input/load requirements to define, and thermal, control-loop and EMI review priorities.
Explore 02 /LDO / Linear Power
Design guidance for low-dropout and linear regulators used on local analog, sensor and control rails. Review dropout, power dissipation, noise/PSRR, capacitor stability and sequencing before choosing a device.
Explore 03 /PMIC / Multi-Rail Power
Power-management IC and multi-rail architecture guidance for controllers and compute systems. Define the rail inventory, startup/shutdown sequence, reset dependencies, always-on functions and fault-response boundaries.
Explore 04 /Battery Charging & Power Path
Architecture guidance for battery charging and the power path between an external source, battery and system load. Define battery requirements, source limits, load priority, source-removal behavior and protection responsibilities.
Explore 05 /Power Protection
Power-front-end guidance for reverse polarity/current, supply transients and overloads. Define the fault conditions, device stresses, energy handling and recovery policy so protection can be reviewed as a system function.
Explore 06 /Smart Power Distribution
Architecture guidance for electronically switched and monitored load channels. Review inrush, smart-switch/eFuse selection inputs, channel diagnostics, fault containment, reset policy and shared thermal limits.
