The RT9680A 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 RT9680A 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 RT9680A keeping the parasitics and their effects to the minimum.<br /><br />The RT9680A is available in a UQFN-11HL 3x3 (FC) package.
