RT8153C/D
Single Phase PWM Controller for CPU Core Power Supply
General Description
The RT8153C/D 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 RT8153C/D adopts G-NAVP (Green
Native AVP), which is a Richtek proprietary topology
derived from finite DC gain compensator constant on-time
mode, making it an easy setting PWM controller which
meets all Intel AVP (Active Voltage Positioning) mobile
CPU/Render requirements. The output voltage of the
RT8153C/D is set by a 7-bit VID code. The built in high
accuracy DAC converts the VID code into a voltage 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 RT8153C/D includes power good and thermal throttling
indicator and an additional clock enabling for CPU core
specification. The soft-start and output transition slew rate
is programmable by an external capacitor. It also features
complete fault protection functions including over voltage,
under voltage, negative voltage, over current and thermal
shutdown. The RT8153C/D is available in WQFN-32L 5x5
and WQFN-32L 4x4 small foot print packages.
