Dual 5V Synchronous Buck Pulse-Width Modulator (PWM) Controller for DDRAM
Rev 2.00
Memory VDDQ and VTT Termination
Nov 15, 2004
The ISL6530 provides plete 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 ISL6530 integrates all of the...
