LMK04828BEVM: Current consumption

Ajmal Rashid

Part Number: LMK04828BEVM
Other Parts Discussed in Thread: LMK04828, , LMK04832, LMX2594

Tool/software:

I'm using the part 'LMK04828B' in my design. Using TICS tool, i can able to calculate the total power consumption of the IC. But, how to calculate ( or how to distribute the total current )the consumption of each VCC pins?
The problem is, i'm using dedicated LDOs ( 500mA output current part) for VCC12_CG0 and VCC4_CG2 for the better isolation between these two groups. But the remaining all VCC pins are planned to power using single LDO which is only capable of maximum 500mA and i'm not sure this is enough for all pins. So please guide me.

Hi Ajmal,

I will answer your question shortly.

Thanks,

Hi Ajmal,

Unfortunately, we do not have this data for the LMK04828BEVM. However, the TICS Pro entry for the LMK04832 does offer information on the current consumption on an individual pin basis. This will not be exactly the same as the individual pin consumption for the LMK04828, but the LMK04832 and LMK04828 are similar enough products that the current calculator for the LMK04832 should provide a good idea of whether or not the single LDO you plan to use will be sufficient for powering the remaining VCC pins.

Thanks,

Michael

Thank you so much. The LMK04832 is consuming little more, but it helped to calculate each pins consumption.

I'm using LMX2594 also in my design, shall I consider the 'approximate current' showing in the tool for the chip consumption?

Yes, that should provide a good estimate of the current consumption.

Thanks,
