Electrical Characteristics

Supply Voltage Characteristics
The TQMxE39S supports an input voltage from 4.75 V to 5.25 V.
The following supply voltages are specified at the SMARC connector:
•
Main Power Rail:
4.75 V to 5.25 V
max input ripple: ±100 mV
•
VCC_RTC:
2.0 V to 3.3 V
max input ripple:
±20 mV
The input voltages shall rise from 10 % of nominal to 90 % of nominal within 0.1 ms to 20 ms (0.1 ms ≤ Rise Time ≤ 20 ms).
There must be a smooth and continuous ramp of each DC output voltage from 10 % to 90 % of its final set point within the
regulation band.
