Description

The FAN50FC3 device is a multi-phase buck switching

regulator controller optimized to convert a 12V input

supply to the processor core voltage required by high-

performance Intel

® processors. It has an internal, 8-bit

DAC that converts a digital voltage identification (VID)

code sent from the processor, to set the output voltage

between 0.5V and 1.6V in 6.25mV steps. It outputs

PWM signals to external MOSFET drivers that drive the

switching power MOSFETs. The switching frequency of

the design is programmable by a single resistor value

and the number of phases can be programmed to

support 2- or 3-phase applications.

The FAN50FC3 also includes programmable no-load

offset and droop functions to adjust the output voltage

as a function of the load current, as required by the

Intel

® specifications. The FAN50FC3 also provides an

accurate and reliable short-circuit protection function

with an adjustable over-current set point.

FastvCore™ technology greatly improves the fast

transient response required by today’s high-performance

processors. This allows fewer output capacitors to be

used in the application.

The FAN50FC3 is specified over the commercial

temperature range of 0°C to +85°C and is available in a

32-lead MLP package.
