DC2575A

Demonstration circuit DC2575A is a 60V 2MHz synchronous buck-boost LED driver featuring the LT8391A. It accepts an input voltage from 4V to 60V and drives a single string of LEDs up to 16V at 1.5A. DC2575A runs at 2MHz switching frequency without spread spectrum, but spread spectrum frequency modulation (SSFM) can be enabled with a simple jumper. SSFM spreads the switching frequency from fSW to fSW + 25% for reduced EMI.
