Adafruit TPS61169 Constant Current Boost Converter for LEDs
Adafruit Industries, LLC mail
The Adafruit Constant Current Boost Converter for LEDs makes driving LEDs easy, whether they're in series or parallel - with a chip that can generate up to 40V and 400mA from 3~5V input. Unlike most of our booster chips that generate a fixed voltage (like 5V, or 12V) the TPS61169 increases the voltage until a set current is being drawn. That makes it excellent for LEDs, that are specified in current not voltage. Perfect for use with our LED nOOds and filaments, where sometimes you need up to 12V or 24V, at 200mA or so. Also excellent when you have a bunch of 3V LEDs in series, so they add up to a high voltage, but only at 25mA or 50mA.
