Description
® RT9682A/B Synchronous Buck Dr.MOS Power Stage General .
The RT9682A/B is a high efficiency synchronous buck power stage module consisting of two asymmetrical MOSFETs and an integrated driver.
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
Applications
* Notebook
* Wireless Charger Solutions
* VCORE and DDR Solutions
