CONTROLLER |
| 摘要 |
A controller (606) for a switched mode power supply (100), comprising: a first terminal (620) for receiving a controller input voltage (Vcc); a second terminal for coupling to ground (654); a selectably engagable load (656); a load selector (658) configured to: engage the selectably engagable load between the first and second terminals in order to draw a selectably engagable load current (lextra), and disengage the selectably engagable load from the first and second terminals in accordance with a comparison between a disengagement threshold and the controller input voltage or an input current at the first terminal. |

1. A controller for a switched mode power supply, SMPS, comprising:
a first terminal for receiving a controller input voltage; a second terminal for coupling to ground; a selectably engagable load; a load selector configured to:
engage the selectably engagable load between the first and second terminals in order to draw a selectably engagable load current, anddisengage the selectably engagable load from the first and second terminals in accordance with a comparison between a disengagement threshold and the controller input voltage or a controller input current at the first terminal. |
