the size and cost of the power supply can be reduced. Higher bandwidth can also improve load transient response. However, higher switching frequency also means higher AC-related power loss, which requires larger board space or a heat sink to limit the thermal stress. Currently...
The well-shorting transistors are turned on when the bus-switch transistor is turned on, but are turned off when the bus-switch transistor is turned off and the bus switch isolates signals on its source and drain. The isolated P-well under the bus-switch transistor and the well-shorting ...
Similarly, the 22µF bypass capacitor ensures clean local power at the LT1070, even during the fast, high current drain periods when VSW comes on. It should have good high frequency character- istics (tantalum or aluminum paralleled by a disc ceramic type). More discussion of these ...
Beside power loop inductance, special attention must be paid to minimizing any capacitance connected from the high-side gate to ground or any other fixed potential, as such a capacitance would directly add to the gate-drain capacitance. Only a few pF could significantly inc...
In order to improve EMI performances, an external Miller capacitor CM is usually mounted between gate and drain of the external FET, as shown in Figure 26. Note that Miller capacitance is always present as a parasitic element: the internal capacitance between transistor gate and drain...
voltage Veoi occurs by means adapted to discharge the capacitor Cign of a small quantity, which means may include a MOS transistor SWsink having the drain terminal connected to a terminal EOI of the capacitor Cign, the source terminal connected to ground GND and the gate terminal driven by ...
The MOTIX™ 6EDL7141 can control the slew rate of the driving signal to control the rise and fall slew rates of the drain-to-source voltage by adjusting the gate drive sink and source currents during different time segments in the switch-on and ...
Loop oscillation frequency increases to keep up with the load's sink current demand. Now, the VC pin waveform (Trace D) begins to take on a filtered ap- pearance. This is due to R1-C1's 10ms time constant. If the load continues to increase, loop oscillation frequency will also ...
This paper describes a high-frequency soft-switching dc-dc converter with a simple energy recovery capacitor snubber on the secondary side. The presented dc-dc full-bridge converter with the energy recovery snubber removes the main drawbacks of the class
