With the transistors shown in Figure 1, the power-supply rejection holds well beyond the audio band. Fig 3. A higher-power ripple-eater augments the simple design with an additional transistor (Q4 ...

After we last saw [David Lovett] of [Usagi Electric], he was knee-deep in trying to fix a DEC PDP-11/03 power supply, which fortunately led to a fixed PSU and a very happy PDP-11/23 system installe… ...

If you decide for the Widlar basic two-transistor design, ... The prototype of Figure 4 has been tested for linearity by connecting the unregulated DC input to a 22V power supply, V control to a ...

GaN power semiconductors from STMicro reduce energy use and enable slimmer designs in a wide variety of electronic products. The company’s G-HEMTs and G-FETs can be used in chargers, external power ...

The DC-DC Converter Handbook authored by David Reusch and John Glaser is intended for power-system designers who employ GaN (gallium nitride) power transistors. It supplements GaN Transistors for ...

Switching transistors from silicon carbide are to increase the efficiency of voltage converters; MSI is installing them in a 1.6-kilowatt power supply unit.

Various charge pumps allow the chip to have several supply options, work with both low-side and high-side GaN transistors, and in two- and three‑level modes. The gate driver IC was fabricated in a ...

Toshiba Corporation (TOKYO:6502) today announced that it has launched an 800V bipolar transistor for switching power supplies of mobile devices that can contribute to reducing standby power ...
