ISL6264CRZ-T

两相核心控制器的AMD移动炫龙处理器 Two-Phase Core Controller for AMD Mobile Turion CPUs

The ISL6264 is a two-phase buck converter regulator with embedded gate drivers. The two-phase buck converter uses two interleaved channels to effectively double the output voltage ripple frequency and thereby reduce output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation, and smaller real estate area. ISL6264 can also be configured as single-phase controller for low power CPU applications.
