WebMay 25, 2024 · Foldback current limit is very similar to the standard upper-boundary limit. But the main goal of foldback current is to limit the total power dissipation, keeping the output transistor within its safe power-dissipation limit by reducing the output current limit linearly while V OUT decreases and V IN remains steady.

Usually output voltage ranges from 2 to 37V. This pin can provide up to 150mA current. Current Limit It is the base input of the current limiter transistor. This pin is used for current limiting or current fold back applications. Current Sense This is the emitter of current limiting transistor. bakrid date 2023WebThe fold-back limiter is more complex compared to a constant current limiter since it requires more electronic components. It also means additional complexity to the linear power supply. Secondly, it does not work well with non-linear loads. Further, a lockout can occur when you use the limiter with a non-ohmic device. bakrid date 2021

"WebAbstract: An over-current protection circuit for improving the integrated regulators' latch-up effect is proposed. Latch-up effect can be eliminated through combining foldback function with constant current limiting function which could change the slope of the foldback current curve to avoid intersecting the static load line.

Fold back current

WebFoldback is a current limiting feature (a type of overload protection) of power supplies and power amplifiers. When the load attempts to draw overcurrent from the supply, foldback reduces both the output voltage and current to well below the normal operating limits. WebThe circuit in Figure 1 incorporates foldback-current limiting to protect the pass transistor by adding feedback resistor R 4. Under normal conditions, transistor Q 2 doesn’t conduct, and resistors R 1 and R 2 bias MOSFET Q 1 into conduction. When an output overload occurs, Q 2 conducts, reducing the on-state bias applied to Q 1 and thus ...
