Patent attributes
A laser diode driver includes a clock terminal to receive a clock signal, configuration terminals to receive configuration data, drive terminals, and charging terminals. A first charging terminal is operable to charge a source capacitor of a resonant circuit that includes the source capacitor, an inductor, and a bypass capacitor. Each drive terminal is operable to be directly electrically connected to an anode or cathode of a laser diode or to ground. A mode, output selection, and grouping of drive signals that are delivered to the laser diodes are configured based on the configuration data. The laser diode driver is operable to control a current flow through the resonant circuit to produce high-current pulses through the laser diodes, the high-current pulses corresponding to a peak current of a resonant waveform developed at respective anodes of the laser diodes, a timing of the high-current pulses being synchronized using the clock signal.
