4. POWER SUPPLY
The power supply circuitry and board layout are a very important part in the complete
product design and they strongly reflect on the overall performance of the product, so
please read carefully the requirements and the guidelines that will follow for a proper
design.
Power Supply Requirements
The external power supply must be connected to VBATT signal and must fulfil the
following requirements:
Power Supply
Value
Nominal Supply Voltage
3.3 V
Supply Voltage Range
3.1 ~ 3.6 V
Max ripple on module input supply
30 mV
Table 9: Power Supply Requirements
Note
: The Operating Voltage Range MUST never be exceeded; care
must be taken when designing the power section of the application
to avoid having an excessive voltage drop.
If the voltage drop exceeds the limits, it could cause the module to
Power Off.
The overshoot voltage (regarding MAX Extended Operating Voltage)
and drop in voltage (regarding MIN Extended Operating Voltage)
MUST never be exceeded;
The “Extended Operating Voltage Range” can only be used with the
complete assumption and application of the HW User guide
suggestions.
Power Consumption
For the complete power consumption specification, please refer to the specific Module’s
Hardware User guide listed in 1.5 Related Documents
General Design Rules
The main guidelines for the Power Supply Design embrace three different design steps:
