Hi, im trying to create a battery powered desk lamp with a flexible LED (3V, <300mA). I'm using a TP4056 charging module with a 3.7V battery.
Components:
1.TP4056 3.7V charging module
2. 3.7V lithium battery
3. Flexible LED filament
4. Touch sensor button (2 wire input, 2 wire output) with DIMMING FUNCTION
5. AMS 1117 module to step down the voltage
I have attached the wiring schematics below.
Problem: if i add the ams module at the output, it is continuously working and drains power from the battery causing the battery to die in 2-3 days. If i add it after the touch switch then problem is resolved but i loose the dimming functionality.
Can someone please provide suggestion on how can i reduce the voltage supply with any power loss while still keeping the dimmer function
