Controller IC Chip - MOSFET ISL62771HRTZ ISL62771 QFN-40 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0512)
Multiphase PWM Regulator for AMD Fusionâ„¢ 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.The PWM modulator is based on Intersil’s Robust Ripple Regulator R3™ Technology. Compared to traditional modulators, the R3 modulator can automatically change switching frequency for faster transient settling time during load transients and improved light-load efficiency.The ISL62771 has several other key features. Both outputs support DCR current sensing with single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. Both outputs utilize remote voltage sense, adjustable switching frequency, OC protection and power-good.
