Abstract:
A pulsed laser diode array driver includes an inductor having a first terminal configured to receive a source voltage, a source capacitor coupled between the first terminal of the inductor and ground, a bypass capacitor connected between a second terminal of the inductor and ground, a bypass switch connected between the second terminal of the inductor and ground, a laser diode array with one or more rows of laser diodes, and one or more laser diode switches, each being connected between a respective row node of the laser diode array and ground. The laser diode switches and the bypass switch are configured to control a current flow through the inductor to produce respective high-current pulses through each row of the laser diode array, each of the high-current pulses corresponding to a peak current of a resonant waveform developed at that row of the laser diode array.
