PWM Dimming Solution Design Instructions

For lamps that require dimming, you only need to connect the PWM pins of the

corresponding color to the control end of the subsequent stage drive circuit; the PWM

independently outputs a 100-level adjustable digital signal, and the subsequent stage circuit

can be voltage The driving type may be a current driving type.

LED Drive Reference Design

TB-02 module application only needs 3.3V power supply and simple driving circuit to

achieve intelligent light control. Take MOS tube to drive a channel of white light as an

example, the design reference is as follows; CW_I is the module's positive white light PWM

output , Q1 is MOS tube, WW is LED lamp beads, the other 4 road lamp driving circuit is the

same as this road design method.
