FAN5019B

6-Bit VID Controller 2-4 Phase VR10.X Controller

Features

General Description

• Improved Noise Immunity

• Improved Load Line Accuracy

• TTL Compatible VID Inputs

The FAN5019B is a multi-phase DC-DC controller for

implementing high-current, low-voltage, CPU core power

regulation circuits. It is part of a chipset that includes exter-

nal MOSFET drivers and power MOSFETS. The

FAN5019B drives up to four synchronous-rectified buck

channels in parallel. The multi-phase buck converter archi-

tecture uses interleaved switching to multiply ripple fre-

quency by the number of phases and reduce input and output

ripple currents. Lower ripple results in fewer components,

lower component cost, reduced power dissipation, and

smaller board area.

• Fully Pin and Function compatible with existing

FAN5019 and ADP3188 Controllers

• Precision Multi-Phase DC-DC Core Voltage Regulation

– ±10mV Output Voltage Accuracy Over Temperature

• Differential Remote Voltage Sensing

• Selectable 2-, 3-, or 4-Phase Operation

• Selectable VRM9 or VRM10 Operation

• Up to 1MHz per Phase Operation (4MHz ripple

Frequency)

• Lossless Inductor Current Sensing for Loadline

Compensation

The FAN5019B features a high-bandwidth control loop to

provide optimal response to load transients. The FAN5019B

senses current using lossless techniques: Phase current is

measured through each of the output inductors. This current

information is summed, averaged and used to set the loadline

of the output via programmable "droop." The droop is tem-

perature compensated to achieve precise loadline character-

istics over the entire operating range. Additionally,

– External Temperature Compensation

• Accurate Loadline Programming (Meets Intel

VRM/VRD10.x CPU Specifications)

• Accurate Channel-Current Balancing for Thermal

Optimization and Layout Compensation

• Convenient 12V Supply Biasing

• 6-bit Voltage Identification (VID) Input

– .8375V to 1.600V in 12.5mV Steps

– Dynamic VID Capability with Fault-Blanking for

glitch-less Output voltage Changes

individual phase current is measured using the R

DS(ON)

the low-side MOSFETs. This information is used to dynam-

ically balance/steer per-phase current. The phase currents

are also summed and averaged for over-current detection.

• Adjustable Over Current Protection with Programmable

Latch-Off Delay. Latch-Off Function may be Disabled

• Over-Voltage Protection – Internal OVP Crowbar

Protection

Dynamic-VID technology allows on-the-fly VID changes

with controlled, glitch-less output. Additionally, short-circuit

protection, adjustable current limiting, over-voltage protec-

tion and power-good circuitry combine to ensure reliable and

safe operation. FAN5019B is specified over the commercial

temperature range of 0°C to +85°C and operates from a sin-

gle +12V supply which simplifies design. FAN5019B is

available in a 28L-TSSOP package.

• Package: 28L-TSSOP

Applications

• VRM/VRD 9.x and 10.x Computer DC/DC Converter

• High-Current, Low-Voltage DC/DC Rail
