General Description

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 RDS(ON) 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.

The RT9680A is available in a UQFN-11HL 3x3 (FC)

package.
