Im trying to power 2 - 1W high power LEDs for a sterilization device. Theres not much room and I am using a pico buck converter for constant voltage to drive the LEDs. I need to have a rechargeable battery that can put out the required 7 volts to drive the buck converter. Is there any options besides putting two bulky lithium ion batteries in series considering Im tight on space?
Hi ramezan. Thanks for your post!
If you don’t want to use more than one battery I’d suggest using a boot converter to turn the 3.7 volts your battery outputs to a higher voltage. Unfortunately we don’t carry a boost converter that would work for you, but something similar to [one of these should do the job for you.](Pololu 9V Step-Up Voltage Regulator U3V12F9)
