ISL6539CAZ-T - Renesas Electronics

Description: 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
