DATASHEET ISL6227 Dual Mobile-Friendly PWM Controller with DDR Option FN9094 Rev 7.00 May 4, 2009 The ISL6227 dual PWM controller delivers high efficiency precision voltage regulation from two synchronous buck DC/DC converters. It was designed especially to provide power regulation for DDR memory, chipsets, graphics and other system electronics in Notebook PCs. The ISL6227’s wide input voltage range capability allows for voltage conversion directly from AC/DC adaptor or Li-Ion battery pack. Automatic mode transition of constant-frequency synchronous rectification at heavy load, and hysteretic (HYS) diode-emulation at light load, assure high efficiency over a wide range of conditions.
