Overview

® ISL6227 Data Sheet March 2004 FN9094.1 Dual Mobile-Friendly PWM Controller with DDR Option 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.

Key Features

Provides regulated output voltage in the range 0.9V.
5.5V.
Operates from an input battery voltage range of 5V to 24V or from 3.3V/5V system rail.
Complete DDR1 and DDR2 memory power solution with VTT tracking VDDQ/2 and a VDDQ/2 buffered reference output.
Flexible PWM or HYS plus PWM mode selection with HYS diode emulation at light loads for higher system efficiency.
rDS(ON) current sensing.
Excellent dynamic response with voltage fee.
