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.
