IP5306 charging pad + LED strip

 This IP5306 charging board, featuring 5050 LED beads and a
2020 aluminum profile lighting strip,
can also be used as an under-cabinet light
. The LED strings can be removed to use it as a battery charging board.
 
 
The LED driver is an OC5219 constant current driver
 
. The OC5219 is a continuous inductor current conduction mode step-down LED constant current driver used to drive one or more LED strings. The OC5219 operates from 5.5V to 30V, providing adjustable output current, with a maximum output current of 1A. Depending on the input voltage and external components, the OC5219 can drive LEDs with power supplies up to tens of watts.
 
Modifying the RCS resistor (R6 in engineering) controls the LED current.
 
The maximum current is 1A, allowing for multiple LED beads to be connected in parallel.
 
However, this requires manual cutting and polishing, which is time-consuming.
