Overview

DATASHEET ISL6539 Wide Input Range Dual PWM Controller with DDR Option FN9144 Rev 6.
00 Apr 29, 2010 The ISL6539 dual PWM controller delivers high efficiency and tight regulation from two voltage regulating synchronous buck DC/DC converters.
It was designed especially for DDR DRAM, SDRAM, graphic chipset applications, and system regulators in high performance applications.
Voltage-feed-forward ramp modulation, current mode control, and internal feedback compensation provide fast response to input voltage and output load transients.
Input current ripple is minimized by channel-to-channel PWM phase shift of 0°, 90° or 180° (determined by input voltage and status of the DDR pin).
