® RT3601EA
Signal Phase PWM Controller with Integrated Driver for
IMVP8 Mobile CPU Core Power Supply
General Description
The RT3601EA is an IMVP8 compliant CPU power
controller with 1 embedded driver. The RT3601EA 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 RT3601EA also features a quick response
mechanism for optimized AVP performance during load
transient. The RT3601EA supports mode transition function
with various operating states. A serial VID (SVID) interface
is built in the RT3601EA to communicate with Intel IMVP8
compliant CPU. The RT3601EA 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 RT3601EA 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 RT3601EA 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
RT3601EA 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 RT3601EA is available
in the WQFN-28L 4x4 small foot print package.
