Constant current step up LED driver for LIPO/LION battery incl. charger
LED driver for single lipo/lion cell with step up (5-28V, 1A) constant current (0.6A, 225mW dissipation) regulator, TP4056 charger (20-1000mA), over-/undervoltage protection (2.5V-4.3V) and a microcontroller.
The circuit output is 7-9.2V (R6+R11/R7) for 3 high power LEDs in series, constant current 30-35mA (R8). P9 needs to be connected to B+ (on) or GND (off). It can also be used to dim the LEDs...
