DATASHEET ISL6531 Dual 5V Synchronous Buck Pulse-Width Modulator (PWM) Controller for DDRAM Memory VDDQ and VTT Termination FN9053 Rev 2.00 Aug 11, 2005 The ISL6531 provides complete control and protection for dual DC-DC converters optimized for high-performance DDRAM memory applications. It is designed to drive low cost N-channel MOSFETs in synchronous-rectified buck topology to efficiently generate 2.5V VDDQ for powering DDRAM memory, VREF for DDRAM differential signalling, and VTT for signal termination. The ISL6531 integrates all of the control, output adjustment, monitoring and protection functions into a single package. The VDDQ output of the converter is maintained at 2.5V through an integrated precision voltage reference.
