ISL6267EVAL1Z中文资料INTERSIL数据手册PDF规格书

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.
