Intersil ISL6227 Dual Mobile-Friendly PWM Controller Datasheet
The ISL6227 is a dual PWM controller designed to provide high-efficiency precision voltage regulation from two synchronous buck converters. It is specifically engineered for power regulation in DDR memory, chipsets, graphics, and other system electronics within Notebook PCs.
Key features include automatic mode transition between constant-frequency synchronous rectification at heavy loads and hysteretic diode-emulation at light loads to ensure high efficiency across a wide range of conditions. The device supports input voltage ranges from 5V to 24V or 3.3V/5V system rails, allowing direct conversion from AC/DC adapters or Li-ion battery packs.
