... Single-Supply Synchronous Buck Converters Standard-to-Synchronous Converter Adaptations GENERAL DESCRIPTION The ADP3412 is a dual MOSFET driver optimized for driving two N-channel MOSFETs which are the two switches in a nonisolated synchronous buck power converter. Each of the drivers is capable of driving a 3000 pF load with propa- gation delay and transition time ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP3412 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... MOSFETs. APPLICATION INFORMATION Supply Capacitor Selection DS(ON) For the supply input (VCC) of the ADP3412, a local bypass capacitor is recommended to reduce the noise and to supply some of the peak currents drawn. Use a 1 µF, low ESR capacitor. Multilayer ceramic chip (MLCC) capacitors provide the best ...

... Trace out the high current paths and use short, wide traces to make these connections. 2. Connect the PGND Pin of the ADP3412 as close as pos- sible to the source of the lower MOSFET. 3. The VCC bypass capacitor should be located as close as possible to VCC and PGND Pins. ...
