Lumissil is well known for its wide range of LED drivers. New to the family is another product that will provide customers with a competitive advantage with their PCBA design. The pressures from end customers to reduce costs is never ending. As lighting systems push toward higher efficiency, smarter controls, and multi function integration, designers need LED drivers that can keep pace with the performance and cost goals. The Lumissil IS32LT3962 answers that challenge with a dual channel synchronous DC DC LED driver engineered for automotive, industrial, and architectural applications.

In battery-powered applications, LED lighting subsystems often receive insufficient attention during power budgeting. Achieving long battery life requires optimizing the complete energy path from battery to light output, including conversion losses, driver quiescent current, and control overhead. LED power must be managed with the same discipline applied to MCU sleep current and wireless standby current. This article examines two Lumissil LED drivers targeting opposite ends of the power spectrum: the IS31BL3557 and the IS31FL3713.
