The supply rails for the selected processor can be generated using discrete or integrated power architecture.
Use of discrete power architecture provides flexibility in design and component selection. Board designer has to take care of the device selection that can source the required load current, setting the output voltage, supply ramp, load transient response and supply sequencing.
Use of integrated power architecture (PMIC) simplifies processor specific power supply design.
The PMIC generates all the common supplies used to power the processor, allows supply power-up and power-down sequencing, supply ramp control and meeting all the processor specific power requirements.
Along with the PMIC, additional DC/DC converters and LDOs are used to generate additional on-board supplies based on use case.
Recommended devices and related collaterals for generating the on-board supplies using different power architectures are summarized below:
