IR3080
Overview
The IR3080 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VRD 10 power solution. The “Control” IC provides overall system control and interfaces with any number of “Phase ICs” which each drive and monitor a single phase of a multiphase converter.
- 6 bit VR10 compatible VID with 0.5% overall system accuracy
- 1 to X phases operation with matching phase ICs
- On-chip 700Ω VID Pull-up resistors with VID pull-up voltage input
- Programmable Dynamic VID Slew Rate
- No Discharge of output capacitors during Dynamic VID step-down (can be disabled)
- +/-300mV Differential Remote Sense
- Programmable 150kHz to 1MHz oscillator
- Programmable VID Offset and Load Line output impedance
- Programmable Softstart
- Programmable Hiccup Over-Current Protection with Delay to prevent false triggering
