General Description

The RT3607CJ 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, the AXG VR. The RT3607CJ

adopts G-NAVPTM (Green Native AVP) 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-NAVPTM

topology, the RT3607CJ also features a quick response

mechanism for optimized AVP performance during load

transient. The RT3607CJ supports mode transition function

with various operating states. A serial VID (SVID) interface

is built in the RT3607CJ to communicate with Intel IMVP8

compliant CPU. The RT3607CJ supports VID on-the-fly

function with three different slew rates : Fast, Slow and

Decay. By utilizing the G-NAVPTM topology, the operating

frequency of the RT3607CJ varies with VID, load and input

voltage to further enhance the efficiency even in CCM.

Moreover, the G-NAVPTM with 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 RT3607CJ 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 RT3607CJ provides VR ready output

signals. It also features complete fault protection functions

including over-voltage (OV), negative voltage (NV), overcurrent

(OC) and under-voltage lockout (UVLO). The

RT3607CJ is available in the WQFN-56L 6x6 small foot

print package.
