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 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 ISL6530 integrates all of the control...
