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.
