ISL54405 - CD/MP3 Quality Stereo 2:1 Multiplexer with Click and Pop Elimination - The Intersil ISL54405 is a single supply, bidirectional, dual single-pole/double-throw (SPDT) ultra low distortion, high OFF-Isolation analog switch that can pass analog signals that are positive and negative with respect to ground. It is primarily targeted at consumer and professional audio switching applications such as Computer Sound Cards and Home Theater products. The inputs can accommodate ground referenced signals up to 2VRMS while operating from a single 3.3V or 5V DC supply. The digital logic inputs are 1.8V logic-compatible when using a single 3.3V or 5V supply. It can be used in both AC or DC coupled ground referenced applications.

ISL6265 - Multi-Output Controller with Integrated MOSFET Drivers for AMD SVI Capable Mobile CPUs - The ISL6265 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 ISL6265 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 ISL6265 can be configured as independent single-phase controllers powering VDD0 and VDD1.
