Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power
A generic fixed inductor for rapid developing circuit topology. *You can now change the footprint and 3D model at the top level anytime you want. This is the power of #generics
@copilot list all ICs and the decoupling capacitors attached to each. Ensure to include all ICs present in the design, including digital ICs, power converters, LDOs, etc. For every IC, clearly state:
What power net the decoupling capacitors are attached to.
The power rating of the attached decoupling capacitors.
Signal with the expression “[WARNING]” if any of the following conditions are met: no decoupling capacitors are attached; the voltage of the power net is higher than the voltage rating of the capacitor; No voltage range was stated for the capacitor. Give a separate “[WARNING]” for each condition. Signal with the expression “[OK]” if none of those conditions are met
Based on the project information provided, there are two (2) Integrated Circuits (ICs) in the project. Here are the details:
IC Designator: U1
Part Name: BME680 (Low power gas, pressure, temperature, and humidity sensor)
Decoupling Capacitor: C11, C12
Attached to Power Net: V_SENSOR
Capacitor Value: 0.1uF each
Voltage range is not supplied for these capacitors.
[WARNING] No voltage rating provided for the capacitors. This needs to be checked to ensure that the capacitors can handle the voltage of the V_SENSOR power net.
IC Designator: IC1
Part Name: ADP5090ACPZ-1-R7 (Battery Chargers)
Decoupling Capacitors: C6, C5, C2
Attached to Power Net: SYS, CBP, VIN respectively
Capacitor Value: 4.7uF for C5 and C6, 0.01uF for C2
Voltage range is not supplied for these capacitors.
[WARNING] No voltage rating provided for the capacitors. This needs to be checked to ensure that the capacitors can handle the voltage of the SYS, CBP, and VIN power nets.
For both these ICs, since there are attached decoupling capacitors and there's no information to suggest that the voltage of the power net is higher than the voltage rating of the capacitor, no further warnings are issued. However, due to the absence of exact voltage ratings of these capacitors, it would be wise to double-check the ratings in relation to the specific power nets these capacitors are connected to.

This information was obtained from the provided project data. It is recommended to revise these ICs and add appropriate decoupling capacitors where needed, also ensure to note down the voltages of the power nets. Some values such as the voltage rating of the capacitors and the voltage of the power net are missing, it is recommended to add these as per the ICs datasheet to avoid potential power issues.
When your power supply is failing to output the correct voltage, consider checking the following aspects of your circuit:
Component values: Ensure that the resistors, capacitors, and inductors have the correct values according to your design.
Soldering quality: Inspect the solder joints for cold or dry solder, shorts, or bad connections.
Input voltage: Verify that the input voltage is within the specified range for your power supply IC (IC1: ADP5090ACPZ-1-R7, IC2: ADP5310AREZN-255R7).
Power supply IC: Make sure you have correctly configured the power supply ICs according to their datasheets. If necessary, re-check the pin connections and configuration settings.
Load current: Ensure that the load current is within the specified limits for your power supply. Excessive load current can cause the output voltage to drop.
PCB layout: A poor PCB layout can lead to noise, instability, or reduced performance. Review your PCB layout to ensure proper grounding, component placement, and trace routing.
Thermal issues: Overheating can cause the power supply to become unstable or shut down. Check if the power supply ICs and other components are operating within their specified temperature range.
Faulty components: Replace suspected faulty components with known good ones to isolate the issue.
Feedback network: If your power supply uses a feedback network to regulate the output voltage, check the connections and component values for correctness.
Oscillation and stability: Verify that your power supply is stable and not oscillating. Oscillations can cause the output voltage to be incorrect. You may need to adjust the compensation network or add a snubber circuit if needed.
