Product Summary
The ISL6227CAZ-T is a dual mobile-friendly PWM controller with DDR option. It delivers high efficiency precision voltage regulation from two synchronous buck DC/DC converters. The ISL6227CAZ-T was designed especially to provide power regulation for DDR memory, chipsets, graphics and other system electronics in Notebook PCs. The wide input voltage range capability allows for voltage conversion directly from AC/DC adaptor or Li-Ion battery pack. The applications of the IISL6227CAZ-T include: Notebook PCs and Desknotes, Tablet PCs/Slates, Hand-Held Portable Instruments.
