Hello Team,
My customer wanted to know the inductor specifications used with the CC1352R when using the internal DCDC converter. This inductor is connected to pin 33, DCDC_SW.
I could not find anywhere on the DS which inductor value, current saturation, current rating, DCR, etc. to use.
Regards,
Renan
Hi Renan,
The recommended value and component can be found our reference design:
LAUNCHXL-CC1352R1 (SWRC345): https://www.ti.com/lit/zip/swrc345
It is important for the customer to use the recommended DCDC inductor (and follow the reference design as closely as possible).
I've listed the current recommended part below for clarity.
| L331 | 6.8uH | INDUCTOR, STANDARD, CHIP, FERRITE CORE, SHIELDED, 6.8uH, -20%/+20%, 1.1A, -55DEGC/+125DEGC, 0805, SMD | TDK | MLZ2012N6R8LT000 |
Regards,
Zack
