RT9680A/B

Synchronous Buck Dr.MOS Power Stage

General Description

Features

^Up to 1MHz Operating Frequency

^For PWM 5V Logic (RT9680A)

^For PWM 3V Logic (RT9680B)

^Input Voltage Up to 23V

The RT9680A/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

R_DS(ON)to minimize conduction losses. A number of

features are provided making the RT9680A/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 RT9680A/B keeping the

parasitics and their effects to the minimum.

^Over-Temperature Protection

^Max Continue Current up to 8A

^Low Quiescent Current

^Tri-State PWM Input

^Integrated Bootstrap Diode

^High Density Package with UQFN-11HL 3x3 (FC)

Applications

 Notebook

 Wireless Charger Solutions

 VCORE andDDR Solutions

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

package.
