LED Flashlight Controller
This reference design employs the PWM block of Zilog’s Z8F082A MCU to control the power and functional modes of an LED flashlight.
This LED Flashlight Controller reference design consists of a single printed circuit board (PCB) featuring Zilog’s Z8F082A MCU in an 8-pin SOIC package, plus resistors, AMC7135 current regulators, a diode, and a capacitor. The PCB is powered by a Lithium-ion battery (3.7 V to 4.2 V) through a battery spring and PCB ground ring. The PCB features four plated through-holes that provide easy access for in-system programming through the spring side of the driver. The 17 mm-diameter dimen-sion of the PCB is suitable for most flashlights available in the market.
