RT3607CE
Multi-Phase PWM Controller for CPU Core Power Supply
General Description
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, the AXG VR. The RT3607CE
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 RT3607CE also features a quick response
mechanism for optimized AVP performance during load
transient. The RT3607CE supports mode transition
function with various operating states. A serial 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 and Decay. By utilizing the G-NAVPTM topology, the
operating frequency of the RT3607CE 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 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.
