DC2575A Demo for LT8391 Buck-Boost LED Controller

Analog Devices Inc. DC2575A Demo for LT8391 Buck-Boost LED Controller provides an evaluation platform for the LT8391 60V 2MHz Synchronous 4-Switch Buck-Boost LED Controller with Spread Spectrum. The DC2575A Demonstration Circuit features the LT8391 LED Controller and AEC-Q automotive-approved components. These AEC-Q automotive-approved components include power MOSFETs, diodes, input and output capacitors, and inductors. The LT8391 has an input voltage from 4V to 60V and drives a single string of LEDs up to 16V at 1.5A. The DC2575A operates at a 2MHz switching frequency without spread spectrum. Designers can enable spread spectrum frequency modulation (SSFM) with a simple jumper. SSFM spreads the switching frequency from f_SW to f_SW+25% for reduced EMI.
