ICC_TDC- 39A
ICC_MAX- 102A
PHASE- 3
SVID- 0x00
DC TOLERANCE- 0.5%
RIPPLE- 6mV

CHANNEL-B
P1V8_AUX
VBOOT- 1.8V
SVID RANGE- STATIC
ICC_TDC- 1.6A

Hi Raj Kumar,

Please find the attached reviewed file. Please check the programming of BSKIP and ASKIP as they are connected to power stages.

Hi Chanakya,

Thank you for the support.

I couldn't find any remark other than ASKIP & BSKIP from your side on the schematic.

Now about the SKIP pins-

Actually, we want to run the VR in FCCM (Forced continues conduction mode). for this reason, we have connected ASKIP & BSKIP to power stage.

Please suggest us, if anything we are missing out??

Thank You

Raj Kumar

Hi Raj Kumar,

Yes, the schematic is fine with respect to all the other pins. It is the SKIP pin I wanted to confirm. Thanks for confirming it.

All the connections are fine in schematic as per the details given by you.

Best regards,
Chanakya.
