Brand New ISL62771 QFN-40 Chip - Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs Using SVI 2.0
The ISL62771 is fully compliant with AMD Fusion SVI 2.0 and provides a complete solution for microprocessor and graphics processor core power. The ISL62771 controller supports two Voltage Regulators (VRs) with three integrated gate drivers. The Core VR supports 2-, or 1-phase configurations while the Northbridge VR supports 1-phase operation. The two VRs share a serial control bus to communicate with the AMD CPU and achieve lower cost and smaller board area compared with two-chip solutions.
Features:
- Supports AMD SVI 2.0 serial data bus interface - Serial VID clock frequency range 100kHz to 25MHz
- Dual output controller with integrated drivers
- Precision voltage regulation - 0.5% system accuracy over-temperature - 0.5V to 1.55V in 6.25mV steps - Enhanced load line accuracy
- Supports multiple current sensing methods - Lossless inductor DCR current sensing - Precision resistor current sensing
- Programmable 1- or 2-phase for the core output
- Adaptive body diode conduction time reduction
- Superior noise immunity and transient response
- Output current and voltage telemetry
- Differential remote voltage sensing
- High efficiency across entire load range
- Programmable VID offset and droop on both outputs
- Programmable switching frequency for both outputs
- Excellent dynamic current balance between phases
- Protection: OCP/WOC, OVP, PGOOD and thermal monitor
- Small footprint 40 Ld 5x5 TQFN package
