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.
