ISL6531EVAL1 [RENESAS]

The ISL6530 and ISL6531 are dual voltage-mode controllers designed for DDR DRAM memory power applications. They feature high-performance error amplifiers, a high-accuracy reference, an internal 50% tracking reference, a fixed 300kHz internal oscillator with 90° phase shift for dual synchronous buck regulators, over-current protection, Power Good indication, and two shutdown options. They include two MOSFET drivers for synchronous-rectified Buck converters and can regulate output voltage while the tracking DC-DC converter is sinking current. The ISL6531 features internal compensation for the VTT regulator. Both ICs are pin-for-pin compatible and available in 24-lead SOIC or 32-lead 4x4mm MLFP packages.
