... POWER MANAGEMENT Description The SC1205 is a cost effective Dual MOSFET Driver de- signed for switching High and Low side Power MOSFETs. Each driver is capable of driving a 3000pF load in 20ns max rise/fall time and has a 20ns max propagation de- lay from input transition to the gate of the power FET’s. ...

... POWER MANAGEMENT Block Diagram Applications Information SC1205 is a high speed, smart dual MOSFET driver designed to drive Low Rds_On power MOSFET’s with ultra-low rise/fall times and propagation delays. As the switching frequencies of PWM controllers is increased to reduce power supply volume and cost, fast rise and fall times are necessary to minimize switching losses (TOP MOSFET) and reduce Dead-time (BOTTOM MOSFET) ...

... FET. This is assuming that the impedance of the drive path is too high compared to the instantaneous imped- ance of the capacitors. (since dV/dT and thus the effec- tive frequency is very high). If the BG pin of the SC1205 is very close to the bottom FET, Vspike will be reduced depending on trace inductance, rate of rise of current, etc ...
