Webdatasheet specification. Consequently, the designer should make all reasonable attempts NOT to operate a MOSFET in avalanche. In reality, in high-current applications, high-voltage switch-off transients are produced due to parasitic inductance in the MOSFET package and PCB traces or leakage inductance from transformers Webcurrent sources. Two current sources are set up for the same currents and a voltage-limiting Zener is placed across each of the current sources. At low voltage, whichever …
Webrent source design, which is a more difficult challenge than a voltage regu-lator design. Current source values of 1mA up to high currents are achiev-able using a single unit or paralleled units. Regulation against line, load and temperature is excellent and unique design techniques have made the de-vice operable without bypass capaci- WebThis application note describes how to use a DS4303/DS4305 to create an inexpensive flexible current source, capable of sourcing or sinking current.
