RT8165B
Dual Single-Phase PWM Controller for CPU and GPU Core
Power Supply
General Description
The RT8165B is a dual single-phase PWM controller with
integrated MOSFET drivers, compliant with Intel IMVP7
Pulse Width Modulation Specification to support both
CPU core and GPU core power. This part adopts G-NAVPTM
(Green-Native AVP), which is a Richtek proprietary topology
derived from finite DC gain compensator in constant on-
time control mode. G-NAVPTM makes this part an easy
setting PWM controller to meet all Intel AVP (Active
Voltage Positioning) mobile CPU/GPU requirements. The
RT8165B uses SVID interface to control an 8-bit DAC for
output voltage programming. The built-in high accuracy
DAC converts the received VID code into a voltage value
ranging from 0V to 1.52V with 5mV step voltage. The
system accuracy of the controller can reach 0.8%. The
RT8165B operates in continuous conduction mode or
diode emulation mode, according to the SVID command.
The maximum efficiency can reach up to 90% in different
operating modes according to different load conditions.
The droop function (load line) can be easily programmed
by setting the DC gain of the error amplifier. With proper
compensation, the load transient response can achieve
optimized AVP performance.
The output voltage transition slew rate is set via the SVID
interface. The RT8165B supports both DCR and sense
resistor current sensing. The RT8165B provides
VR_READY and thermal throttling output signals for
IMVP7 CPU and GPU core. This part also features
complete fault protection functions including over voltage,
under voltage, negative voltage, over current and thermal
shutdown.
The RT8165B is available in a WQFN-40L 5x5 small
footprint package.
