Features

General Description

• Pin and Function Backward Compatible with FAN53168

and FAN53180 Controllers

The FAN5019 is a multi-phase DC-DC controller for imple-

menting high-current, low-voltage, CPU core power regula-

tion circuits. It is part of a chipset that includes external

MOSFET drivers and power MOSFETS. The FAN5019

drives up to four synchronous-rectiﬁed buck channels in par-

allel. The multi-phase buck converter architecture uses inter-

leaved switching to multiply ripple frequency 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.

• 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

– External Temperature Compensation

• Accurate Load-Line Programming (Meets Intel^®

VRM/VRD10.0 and 10.X CPU Speciﬁcations)

• Accurate Channel-Current Balancing for Thermal

Optimization and Layout Compensation

• Convenient 12V Supply Biasing

The FAN5019 features a high bandwidth control loop to

provide optimal response to load transients. The FAN5019

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,

• 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

• Adjustable Over Current Protection with Programmable

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

• Over-Voltage Protection – Internal OVP Crowbar

Protection

individual phase current is measured using the R_DS(ON)of

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.

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. The operating temperature range is 0°C to

+85°C and the operating voltage is a single +12V supply,

which simpliﬁes the design. The FAN5019 is available in a

TSSOP-28 package.

Applications

• Computer DC/DC Converter VRM/VRD10.0

• Computer DC/DC Converter VRM/VRD10.X

• Computer DC/DC Converter VRM/VRD9.X

• High Current, Low Voltage DC/DC Rail
