CURRENT LIMITING CIRCUIT AND METHOD FOR LED DRIVER

摘要

Circuit that includes a driver circuit (160) and a current limiter circuit (170). The driver circuit (160) is configured to drive a load (169) with an output current (II) when the load (169) is coupled with the driver circuit (160). The current limiter circuit (170) is configured to turn on a path to deplete a portion (13) of the output current (II) from the driver circuit (160) in order to prevent a load current (12) flowing through the load from exceeding a current limit.
