RT3607CE

Multi-Phase PWM Controller for CPU Core Power Supply

General Description

Features

^Intel IMVP8 Serial VID Interface Compatible Power

The RT3607CE is an IMVP8 compliant CPU power

controller which includes two voltage rails : a 4/3/2/1 phase

synchronous Buck controller, the CORE VR, a 3/2/1 phase

synchronous Buck controller, theAXGVR. The RT3607CE

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^TM

topology, the RT3607CE also features a quick response

mechanism for optimized AVP performance during load

transient. The RT3607CE supports mode transition

function with various operating states.Aserial VID(SVID)

interface is built in the RT3607CE to communicate with

Intel IMVP8 compliant CPU. The RT3607CE supports VID

on-the-fly function with three different slew rates : Fast,

Slow andDecay. By utilizing theG-NAVP^TMtopology, the

operating frequency of the RT3607CE varies with VID, load

and input voltage to further enhance the efficiency even in

CCM. Moreover, theG-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 0.25V to 1.52V with 5mV per step. The RT3607CE

integrates a high accuracy ADC for platform setting

functions, such as quick response trigger level or over-

current level. Besides, the setting function also supposes

this two rails address exchange. The RT3607CE provides

VR ready output signals. It also features complete fault

protection functions including over-voltage (OV), negative

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

(UVLO). The RT3607CE is available in the WQFN-56L

6x6 small foot print package.
