PMIC Passive Placement: Start from the Input Pins
Using TI placement guidance to organise the relationship among PMIC capacitors, inductors and output rails.
Details
Back to listThe input side is the placement start
TI PMIC layout guidance places input capacitors close to the PMIC input pins and prioritises same-layer connection before the remaining output-rail placement is developed.
Relationships to confirm
- PMIC input pins, input capacitors and ground connection
- Output components and load direction for each voltage rail
- Isolation needs between power areas and clock, analog or high-speed signals
Project material
Supplying the PMIC part number, typical application circuit, required rails and load priorities helps establish an initial layout that can be reviewed.
