Description
The RT3602AE is an IMVP8 compliant CPU power
controller which includes three voltage rails : a 2/1 phase
synchronous Buck controller, the MAIN VR, a single phase
synchronous Buck controller, the auxiliary VR, and a
single phase synchronous Buck controller, the VCCSA
VR. The RT3602AE 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 GNAVPTM
topology, the RT3602AE also features a quick
response mechanism for optimized AVP performance
during load transient. The RT3602AE supports mode
transition function with various operating states. A serial
VID (SVID) interface is built in the RT3602AE to
communicate with Intel IMVP8 compliant CPU. The
RT3602AE 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
RT3602AE varies with VID, load and input voltage to further
enhance the efficiency even in CCM. Moreover, the GNAVPTM
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 RT3602AE integrates a high
accuracy ADC for platform setting functions, such as quick
response trigger level. Besides, the setting function also
supposes this two rails address exchange. The RT3602AE
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 RT3602AE is available in the WQFN-
48L 6x6 small foot print package.
