● Common Anode
When adopting a common anode architecture, N LED strip lights are joined in parallel, and only N+1 wires are needed to connect them.
This is less than the LED wires required for conventional power structures (2N), and can greatly improve the mechanism design, reducing the product size and wiring costs. However, with that being said, this structure still does not solve the problem of having too many LED driver circuits.
● Advantages of SIMO (Single Inductor Multiple Outputs) Structures
1. Reducing driver circuit numbers to 1/4
2. Only N+1 wires needed for 4-color dimming
3. Good dimming linearity
Due to its featured single-inductor-multiple-output and common-cathode structure advantages, the SIMO structure is much superior in the product size, cost, and functions when compared to conventional hysteretic buck chip and common-anode power structures. Under specific application specifications, the SIMO structure is certain to tremendously improve the price-performance ratio for modern stage lighting designs. Without a doubt, this structure is the new solution choice for LED stage lighting applications.
● MOSFET Integration within Driver
Simplify component counts and PCB layouts.
● PWM Dimming
Provide a better light performance. In general, 200Hz dimming frequency is enough to prevent flicker problem, but in the application of stage lighting, the dimming frequency must be higher than 2kHz to prevent the visible flicker from camera.
