POWER SUPPLY
The power supply circuitry and board layout are a very important part in the full product
design and strongly reflect on the product overall performances, so please read carefully
the requirements and guidelines that will follow for a proper design
.
Power Supply Requirements
The external power supply must be connected to 3V3_AUX signal and must fulfil the
following requirements:
Parameter
Values
Nominal Supply Voltage
3.3V
Supply Voltage Range
3.0V ~ 3.6V
Max ripple on module input supply
30mV
Table 7: Power Supply Requirements
Note: The Operating Voltage Range MUST never be exceeded; care
must be taken when designing the power supply section of the
application to avoid having an excessive voltage drop.
If the voltage drop exceeds the limits it could cause a Power Off of the
module.
The Overshoot voltage (regarding to the MAX Extended Operating
Voltage) and drop in voltage (regardingto the MIN Extended Operating
Voltage) MUST never be exceeded.
The “Extended Operating Voltage Range” is intended as the worse case
between this document and those related to the module mounted and
can only be used in non standard mPCIe application, custom design,
with completely assumption and application of the HW User Guide
[5]
suggestions.
Power Consumption
For the complete power consumption specification, please refer to the specific Module’s
HW User Guide
