POWER MANAGEMENT

PRELIMINARY

.igure 3: Rise and fall time and propagation delay of SC1205H, driving two top

and two bottom .ETs, All .ETS , .DB7030BL

Rise and fall time of gate drives of the SC1205H with

VCC = VBST = +8V.

Ch1:Top gate drive, Ch2:Bottom Gate drive

Note that these rise and fall times are achieved while

driving 2X .DB7030BL MOS.ETs on top and 2X

.DB7030BL on the bottom (synchronous).

Vin = 5V

Vcc = Vbst = 8V

Iout = 20A/phase

All gate drive resistors are set to zero for this test.
