PIC16F1769 Dual Independent-Channel Power Supply Demonstration • The PIC® MCU uses its on-chip peripherals to create independent, closed-loop channels. Independently

controls two LED strings, and automatically adjust modes (ON/OFF, blink, strobe, fade and auto), which

displays the capability of multiple independent channels in a simple 8-bit MCU design.

• Hardware-based solution reduces latency, increases system performance, eliminates discrete

components and frees the CPU to perform the task of driving the LED array.
