NCP5378  
Single Phase Synchronous  
Buck Controller with  
Integrated Gate Drivers and  
Programmable DAC  
http://onsemi.com  
The NCP5378 is a single chip solution which combines differential  
voltage sensing, differential phase current sensing, adaptive voltage  
positioning, and on board gate drivers to provide accurately regulated  
power for Intel processors. This controller IC maintains the same  
features as the multi−phase product family, but reduces the output to a  
single−phase, for lower current systems. Low power mode operation  
combined with inductor current sensing reduces system cost by  
providing the fastest initial response to dynamic load events.  
The gate drive adaptive non overlap and power saving operation  
circuit can provide a low switching loss and high efficiency solution  
for notebook and desktop systems. A high performance operational  
error amplifier is provided to simplify compensation of the system.  
Dynamic Reference Injection further simplifies loop compensation by  
eliminating the need to compromise between closed−loop transient  
response and Dynamic VID performance.
