High Current, Low Dropout Driver Circuit
This abstract first appeared for US patent application 20240431001 titled 'High Current, Low Dropout Driver Circuit
Original Abstract Submitted
a high current, low dropout driver circuit is disclosed. the circuit includes a decoder configured to decode a plurality of control bits to generate a plurality of control signals, and a current source having a plurality of devices. the current source is configured to activate at least a subset of the plurality of devices using the control signals to provide a load current to a load circuit, such as a light-emitting diode (led), using activated ones of the plurality of devices and a control voltage. a control circuit is configured to generate the control voltage based on the load current and a reference current.
