RT8152E/F
Single-Phase PWM Controller for CPU / GPU Core Power
Supply
General Description
The RT8152E/F is a single phase PWM controller with
integrated MOSFET drivers. Moreover, it is compliant with
Intel IMVP6.5 Voltage Regulator Specification to fulfill its
mobile CPU core and Render core voltage regulator
requirements. The RT8152E/F adopts G-NAVP (Green-
Native AVP), which is a Richtek's proprietary topology
derived from finite DC gain compensator constant on-time
mode, making it an easy setting PWM controller meeting
all Intel AVP (Active Voltage Positioning) mobile CPU/
Render requirements. The output voltage of the RT8152E/
F is set by 7-bit VID code. The built-in high accuracy DAC
converts the VID code ranging from 0V to 1.5V with
12.5mV per step. The system accuracy of the controller
can reach 1.5%. The part supports VID on-the-fly and mode
change on-the-fly functions that are fully compliant with
IMVP6.5 specification. It operates in single phase and
diode emulation modes. It can reach up to 90% efficiency
in different modes according to different loading conditions.
The droop load line can be easily programmed by setting
the DC gain of the error amplifier. W ith proper
compensation, the load transient can achieve optimized
AVP performance. This chip controls soft-start and output
transition slew rate via a capacitor. It supports both DCR
and sense resistor current sensing. The RT8152E/F
provides power good and thermal throttling output signals
for IMVP6.5 Render core specification, and additional clock
enabling for CPU core specification. It also features
complete fault protection functions including over voltage,
under voltage, negative voltage, over current and thermal
shutdown. The RT8152E/F is available in WQFN-32L 5x5
small foot print package.
