Key design challenges when designing smart meter systems
Power consumption profile for typical flow meters
Best practices for designing meters with a buck-boost converter
Best practice No. 1: Limit the peak current drawn from the battery.
Best practice No. 2: Make the output and input voltage levels independent.
Best practice No. 3: Use converters with a low operating current and a standby current below 500 nA.
Best practice No. 4: Keep the voltage of the supply system as low as possible.
Best practice No. 5: Optimize voltage load per operating mode with dynamic voltage scaling.
