5S2P AR111 LED light driver reference design

Overview

This reference design uses MAX16819 as the main controller to provide a buck-boost driver solution for the 5S2P AR111 LED lamp. Figure 1 is the circuit schematic diagram, and Figure 2 shows the design layout.

The following are the electrical input requirements and output characteristics:

V _IN : 12VAC ±10%
PWM input: N/A
V _LED configuration: 5S2P, each LED voltage is 3VDC to 3.8VDC (19VDC per string, maximum), each string current 500mA
