GENERAL DESCRIPTION
Based on the GNAVPTM topology, the RT3612EB features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. A serial VID (SVID) interface is built in the RT3612EB to communicate with Intel IMVP9 compliant CPU. The RT3612EB supports VID on-the-fly function with three different slew rates: Fast, Slow and Decay. By utilizing the G-NAVPTM topology, the operating frequency of the RT3612EB varies with VID, load and input voltage to further enhance the efficiency even in CCM. Moreover, the G-NAVPTM with CCRCOT (Constant Current Ripple COT) technology provides superior output voltage ripple over the entire input/output range. The built-in high accuracy DAC converts the SVID code ranging from 0V to 2.74V with 10mV per step. The RT3612EB integrates a high accuracy ADC for platform and function settings, such as ICCMAX, switching frequency, over-current threshold and AQR trigger level.
