The RT9682A/B is a high efficiency synchronous buck power stage module consisting of two asymmetrical MOSFETs and an integrated driver. The MOSFETs are individually optimized for operation in the synchronous buck configuration. The high side MOSFET has low capacitance and gate charge for fast switching with low duty cycle operation. The low side MOSFET has ultra low R<sub>DS(ON)</sub> to minimize conduction losses. A number of features are provided making the RT9682A/B a highly versatile power module. The boot strap diode is integrated in the driver. The low-side MOSFET can be driven into diode emulation mode to provide asynchronous operation to improve light load efficiency. The pin-out is optimized for low inductance routing of the RT9682A/B keeping the parasitics and their effects to the minimum. <p align="justify">The RT9682A/B is available in a UQFN-11HL 3x3 (FC) package.</p>
