Hi ,
Kindly review the design and configuration file for our 4 phase 1V supply using UCD9224 and UCD74111.
The specs for the design are:
1. 12V to 1V @ 48 A (SoC requires only 40A)
2. 4 phases at switching frequency of 700KHz
3. No phase shedding at low loads
4. Current sensed using 2mOhm sense resistor
5. 1V Enabled using the the seq1 pin (Active High)
Schematic:[
Configuration:
Also, Please share with me any documents about layout guidelines for the power driver UCD74111.
Thanks
Ashok
