ISL6265AHRTZ-T集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

The ISL6265A is a multi-output controller with embedded gate drivers. A single-phase controller powers the Northbridge (VDDNB) portion of the CPU. The two remaining controller channels can be configured for two-phase or individual single-phase outputs. For uniplane CPU applications, the ISL6265A is configured as a two-phase buck converter. This allows the controller to interleave 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 area. For dual-plane processors, the ISL6265A can be configured as independent single-phase controllers powering VDD0 and VDD1.
