The TPS51518 is  
a
single phase, D-CAP™/  
•
Adaptive On-Time Modulation with Selectable  
Control Architecture  
D-CAP2™ synchronous buck controller with 2-bit VID  
inputs which can select up to four independent  
externally programmable output voltage levels where  
full external programmability in the voltage level, step  
setting and voltage transition slew rate is desired. It is  
used for GFX applications where multiple voltage  
levels are desired.  
–
D-CAP™ Mode at 350 kHz for Fast  
Transient Response  
–
D-CAP2™ Mode at 350 kHz for  
Ultra-Low/Low ESR Output Capacitor
