Step-by-Step Design Process for the MAX16833 High-Voltage High-Brightness LED Driver, Part 2

This application note details a step-by-step design process for the MAX16833 high-voltage high-brightness LED driver. This process can speed up prototyping and increase the chance for first-pass success. A typical design scenario is presented, along with example calculations based on the design constraints. Component selection trade-offs are discussed. A spreadsheet calculator (XLS) is included to help calculate external component values. This application note focuses on the buck-boost converter topology. However, the same process can be applied to other topologies as long as the underlying equations are understood. For a boost converter design example, see application note 5571, “Step-by-Step Design Process for the MAX16833 High-Voltage High-Brightness LED Driver, Part 1.”
