摘要： In a driver circuit couplable to laser diodes, a semiconductor body has a first surface. First and second control switches have drains coupled to a drain metallization, which is couplable to a power supply line, and sources coupled to respective first and second source metallizations, which are couplable to cathode terminals of the laser diodes and a reference node. A plurality of high-side switches have drains coupled to the drain metallization and sources coupled to third source metallizations, each of which is coupled to a respective drive output node for driving an anode terminal of a respective laser diode. The drain, first, second and third source metallizations face the first surface of the semiconductor body, which faces the laser diodes. The second and third source metallizations are aligned with one another and are superimposed to the respective source terminals of the second control switch and high-side switches.

摘要： An embodiment pulse generator circuit comprises a first electronic switch coupled between first and second nodes, and a second electronic switch coupled between the second node and a reference node. An LC resonant circuit comprising an inductance and a capacitance is coupled between the first and reference nodes along with charge circuitry comprises a further inductance in a current flow line between a supply node and an intermediate node in the LC resonant circuit. Drive circuitry of the electronic switches repeats, during a sequence of switching cycles, charge time intervals, wherein the capacitance in the LC resonant circuit is charged via the charge circuit, and pulse generation time intervals, wherein a pulsed current is provided to the load via the first and second nodes. The charge and pulse generation time intervals are interleaved with oscillation time intervals where the LC resonant circuit oscillates at a resonance frequency.
