The RT8153 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 RT8153 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 RT8153 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. </p>The RT8153 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 RT8153 is available in WQFN-32L 5x5 and WQFN-32L 4x4 small foot print packages.</p>
