LMX2582: Query on Current consumption calculation

Narender Mariappan
Intellectual 280 points

Part Number: LMX2582

Tool/software:

HI,

We have a query with LMX2582 Current consumption . Typical current consumption is given as 250 mA.(Provided in datasheet)

 

  1. Should have to include "CHDIV_DISTB_EN", "OUTA_PD" and "OUTB_POW" in the calculation?
  2.  What is the current consumption if "OUTA_POW = 15" instead of 63 ??
  3. Should Charge pump current also to be included ?? We are using 4.843 mA - Charge Pump Current.
  4. Does the 250 mA includes "Table 8-2. Typical Current Consumption Impact By Function"  or do we have to add the current individually with 250 mA  based on the functions we use.

I have attached TICS pro SW  and current calculations FYR. Based on the my Calculations, current consumption is 440 mA . Kindly check and confirm correct way to calculate current consumption and what will be the exact values.
