    摘要: An electronic device (1000) couplable to a plurality of laser diodes (LD_j) and comprising a semiconductor body (504) including: a control switch (S1) having a drain (DS1) coupled to a drain metallization (530) and having a source (SS1) coupled to a first source metallization (532) electrically couplable to cathodes (LDc_j) of the laser diodes (LD_j); a respective plurality of first switches (S2_j), each first switch (S2_j) having a drain (DS2_j) coupled to the drain metallization (530) and having a source (SS2_j) coupled to a respective second source metallization (534_j) couplable to an anode (LDa_j) of one of the laser diodes (LD_j). The second source metallizations (534_j) are aligned with one another in a direction of alignment (520), overlie, in a direction orthogonal to the direction of alignment (520), the respective sources (SS2_j) of the first switches (S2_j), and can be aligned, in a direction orthogonal to the direction of alignment (520), to the respective laser diodes (LD_j). At least one of the sources (SS2_j) of the first switches (S2_j) can be aligned, in a direction orthogonal to the direction of alignment (520), to the respective laser diode (LD_j).
