Based on a buck topology switching power supply, this system maximizes the transference of energy between a battery and a high-brightness LED. The PROMOTORCH board supports general-purpose 908QB8 8-bit MCUs.
- Provides luminosity intensity control, and measures the current (via 10-Bit resolution ADC)
- Helps to maintain an accurate constant current for color integrity
- Enables accurate measurements of the shunt resistor current
- Includes an internal band-gap reference for monitoring battery voltage for brightness compensation and system battery level
