Abstract
The invention relates to a system for generating an output voltage (Vout) from an input voltage (Vup), said system comprising:—regulation means (T1) for regulating said output voltage (Vout) to a target voltage level (Vcons), said regulation means (T1) comprising a control terminal intended to receive a regulation signal (SR) and an output terminal for delivering said output voltage (Vout),—first control means (COMP1) for delivering a first control signal (SC1) from a comparison between said regulation signal (SR) and a first reference signal (Vref1).
Claims5
A system for generating an output voltage from an input voltages, said system comprising:
- regulation means for regulating said output voltage to a target voltage level, said regulation means comprising a control terminal that receives a regulation signal and an output terminal for delivering said output voltage;
- first control means for delivering a first control signal from a comparison between said regulation signal and a first reference signal, the first control signal forming an indication that the regulation signal is outside a normal range;
- and
- second control means for delivering a second control signal from a comparison between a fraction of the current delivered by said regulation means on said output terminal and a second reference signal, the second control signal forming an indication that an output current is outside a normal range.
