Controller IC Chip - MOSFET ISL6267HRZ ISL6267 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0509) Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs The ISL6267 is designed to be completely compliant with AMD Fusion™ specifications. The ISL6267 controls two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be configured as 3-, 2-, or 1-phase VR, while the second output can be configured as 2- or 1-phase VR, providing maximum flexibility. The two VRs share the serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with two-chip solutions.The PWM modulator of ISL6267 is based on Intersil’s R3 (Robust Ripple Regulator) Technology™. Compared with the traditional multi-phase buck regulator, the R3 modulator commands variable switching frequency during load transients, achieving faster transient response. With the same modulator, it naturally goes into pulse frequency modulation in light load co
