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… ...

Four forms of power supplies are widely used today: unregulated, ferroresonant, series-regulated, and switching-regulator types. Differences include maintaining constant voltage output, cost ...

where D is the duty cycle of the buck switch Q1 in Figure 6.When the low-side synchronous switch Q2 conducts, V P is reflected to secondary and rectified as V OUT.The equivalent circuit is shown in ...

For both designs, the regulating element is realised using a power pass-transistor operating in its active region, e.g., where IC = βIB. Conceptually, this transistor can be considered as a ...

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 ...

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 ...
