I have been looking at specialty bike light applications for about a year now. Specifically, a daytime and night time high brightness flash application for a red tail light.
I wanted to apply a constant light along with flash modes. I have not found this in commercially available drivers. This modification allows for a 350ma constant output where various modes can "ride" on top of this constant mode.
The base driver is the NANJG 101-AK driver, in this case, the 17-mode version. The reason for choosing this driver was the special modes including 1Hz, 1/3Hz, 10 second beacon, and a special police mode. Still applicable are the constant modes which add on top of the 350ma minimum.
The trace to the right AMC7135 gate was cut (small circle). The gate was then re-routed to the protection diode output (red rectangle). This provides full drive to the AMC7135 when power is applied.
Variations are easy to envision because these are 1400ma drivers. Here, the driver is configured for 1050ma and the constant modes would be as follows:
low - 350ma +5% of 700ma = ~385ma
med - 350ma +30% of 700ma = ~560ma
High - 350ma +100% of 700ma = ~1050ma
Adding additional AMC7135 will obviously change these numbers but you get the idea.
