Abstract

The present disclosure provides a multi-mode dimming control method and a dimming circuit. The multi-mode current control method includes: receiving a dimming signal, and controlling the dimming circuit to be operated in a plurality of modes in an arbitrary order according to the dimming signal, wherein the plurality of modes include any two or all of a first dimming mode, a second dimming mode, and a third dimming mode. Also, the dimming circuit can be operated in different combinations of different modes according to actual needs, so that the requirements of a wide dimming range and a low output current ripple can be realized.
