RT8170A
Single-Phase Controller with Integrated Driver for VR12.5
and VR12.6 Mobile CPU Core Power Supply
General Description
The RT8170A is a single phase CPU power controller with
one integrated driver for VR12.5 and VR12.6 compliant.
The RT8170A adopts the G-NAVP
TM
(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-
NAVP
TM
topology, the RT8170A also features a quick
response mechanism for optimized AVP performance
during load transient. The RT8170A supports mode
transition function with various operating states. A Serial
VID (SVID) interface is built in the RT8170A to
communicate with Intel VR12.5 and VR12.6 compliant
CPU. The RT8170A supports VID on-the-fly function with
different slew rates. By utilizing the G-NAVP
TM
topology,
the operating frequency of the RT8170A varies with VID,
load current and input voltage to further enhance the
efficiency even in CCM. Besides the G-NAVP
TM
, the
CCRCOT (Constant Current Ripple Constant On Time)
technology provides superior output voltage ripple over
the entire input/output range. The built-in high accuracy
DAC converts the SVID code ranging from 0.5V to 3.04V
with 10mV per step. The RT8170A integrates a high
accuracy ADC for platform setting functions, such as no-
load offset and over-current protection level. The RT8170A
provides VR ready output signals. It also features complete
fault protection functions including Over-Voltage (OV),
Under-Voltage (UV), Negative-Voltage (NV), Over-Current
(OC) and Under-Voltage Lockout (UVLO). The RT8170A
is available in the WQFN-32L 4x4 small foot print package.
