RT3613EB

3-Phase PWM Controller with Dual Integrated Drivers for

IMVP9 CPU Core Power Supply

General Description

Features

^Intel IMVP9 Serial VID Interface Compatible Power

The RT3613EB is a 3/2/1 phase synchronous buck

controller designed to meet Intel IMVP9 compatible CPU

specification with a serial VID control interface. The

RT3613EB adoptsG-NAVP^TM(GreenNativeAVP) which

is Richtek's proprietary topology derived from finite DC

gain of EA amplifier with current mode control, making it

easy to set the droop to meet all Intel CPU requirements

of AVP (Adaptive Voltage Positioning). Based on the G-

NAVP^TMtopology, the RT3613EB features a new

generation of quick response mechanism (Adaptive Quick

Response,AQR) to optimizeAVP performance during load

transient and reduce output capacitors. The RT3613EB

supports mode transition function with various operating

states. A serial VID (SVID) interface is built in the

RT3613EB to communicate with Intel IMVP9 compliant

CPU. The RT3613EB supports VID on-the-fly function with

three different slew rates: Fast, Slow and Decay. By

utilizing theG-NAVP^TMtopology, the operating frequency

of the RT3613EB varies with VID, load and input voltage

to further enhance the efficiency even in CCM. Moreover,

the G-NAVP^TMwith CCRCOT (Constant Current Ripple

COT) technology provides superior output voltage ripple

over the entire input/output range. The built-in high accuracy

DAC converts the SVID code ranging from 0V to 2.74V

with 10mV per step. The RT3613EB integrates a high

accuracyADC for platform and function settings, such as

ICCMAX, switching frequency, over-current threshold and

AQR trigger level. The RT3613EB provides VR Ready and

thermal indicators. It also features complete fault

protection functions including over-voltage (OV), under-

voltage (UV), over-current (OC) and under-voltage lockout

(UVLO).
