Design An Adaptable Power Supply For XENPAK:
03/17/03 Electronic Design - Ideas for Design /
XENPAK is a multisource agreement (MSA) for a
10-Gbit transceiver package. As part of the XENPAK
MSA, each XENPAK module requires input power from an
adaptable power supply (APS) that resides on a
backplane. ...
Variable load tests voltage sources: 07/19/2001
EDN - Design Ideas / The circuit in Figure 1 serves
as a variable, current-sink load for testing voltage
sources. You use digital commands to set the load
current of the device under test over a wide range,
independently of the device under test's output
voltage.
Varying Brightness AC Lamp: SCR is used to
slowly vary the intensity of a120 volt light bulb by
controlling the Time that the AC line voltage is
applied to the lamp during each half cycle
