IR3521
Overview
The IR3521 Control IC combined with an xPHASE3TM Phase IC provides a full featured and flexible way to implement a complete AMD SVID power solution. It provides outputs for both the VDD core and VDDNB auxiliary planes required by the CPU.
- 2 converter outputs for the AMD processor VDD core and VDDNB auxiliary planes
- Supports High Speed (HS) I2C Serial communications
- PSI_L serial commands are communicated to a programmable number of phase ICs
- 0.5% overall system set point accuracy
- High speed error amplifiers with wide bandwidth of 20MHz and fast slew rate of 10V/us
- Remote sense amplifiers provide differential sensing and require less than 50uA bias current
- Programmable Dynamic VID Slew Rates
- Programmable VID Offset (VDD output only)
- Programmable output impedance (VDD output only)
- Programmable Dynamic OC for IDD_Spike
