RT3602AP  
Triple Channel PWM Controller for IMVP8 Mobile CPU Core  
Power Supply  
General Description  
Features  
Intel IMVP8 Serial VID Interface Compatible Power  
The RT3602AP is an IMVP8 compliant CPU power  
controller which includes three voltage rails : a 2/1 phase  
synchronous Buck controller, the MAINVR, a single phase  
synchronous Buck controller, the auxiliary VR, and a  
single phase synchronous Buck controller, the VCCSA  
VR. The RT3602AP adoptsG-NAVPTM (GreenNativeAVP)  
which is Richtek's proprietary topology derived from finite  
DC gain of EAamplifier 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 RT3602AP also features a quick  
response mechanism for optimized AVP performance  
during load transient. The RT3602AP supports mode  
transition function with various operating states. A serial  
VID (SVID) interface is built in the RT3602AP to  
communicate with Intel IMVP8 compliant CPU. The  
RT3602AP 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  
RT3602AP 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 SVIDcode ranging from 0.25V to 1.52V  
with 5mV per step. The RT3602AP integrates a high  
accuracyADC for platform setting functions, such as quick  
response trigger level. The RT3602AP 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 RT3602AP is available in the WQFN-48L 6x6 small  
foot print package.
