Renesas ISL62771 62771 QFN-40

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
