RT9682B - Synchronous Buck Dr.MOS Power Stage

This page provides the datasheet information for the RT9682B, a member of the RT9682A Synchronous Buck Dr.MOS Power Stage family.

Description

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.

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. The RT9682A/B is available in a UQFN-11HL 3x3 (FC) package. Ordering Information RT9682A/B Package Type QUF : UQFN-11HL 3x3 (F.

® RT9682A/B Synchronous Buck Dr.MOS Power Stage General Description 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 RDS(ON) 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.
