[chbot] Boost converter with constant current output

[Volker Kuhlmann]

Has anyone come across a boost converter module with constant current
output 1-20mA by any chance and remembers where? Input voltage one
lithium cell (2.5-4.5V roughly), output voltage 10-30V or so, but
constant current.

It is trivial to find boost converter modules with constant voltage
output, and constant current for beefy LED drivers (350-700mA), but I am
looking for something <0.5W, or perhaps <1W.

Thanks muchly,

Volker
