We calculated the power consumption for designing our board.
Because inconsistency arose, I want someone to solve the riddle.
a) Based on the data sheet, the maximum output current of DCDC_VDD is 250mA(MIN).
b) When a Core clock is 454.73MHz according to i.MX28 Power Consumption Caliculator, the power consumption of Core is 408.43mW and the current is 263.5mA ( = 408.43mW / 1.55V ).
When the clock of Core is the maximum, can't needed current be supplied to Core only by a built-in regulator?
Is the supply from the outside needed?
Please let me know what kind of way of thinking is correct.
