General Description
The RT9256 is an analogous current mode design and is specifically promoted for high power density consideration platform with MLCC capacitor attached, such as high-end add-on graphic card core power and DDR SDRAM core power, etc. A highlight for RT9256 is the RichTek’ s new innovation of actively alternative mode operation two-phase power conversion or dual PWM controller operation. Based on above innovation architecture, the RT9256 provides more flexibility and higher performance to customer application.
