Overview
Product Details
Demonstration circuit 2345A is a 60V synchronous 4-switch buck-boost LED controller with spread spectrum featuring the LT8391 LED driver. It accepts an input voltage from 4V to 60V and drives a single string of LEDs up to 25V at 2A. DC2345A runs at 400kHz switching frequency without spread spectrum, but spread spectrum frequency modulation (SSFM) can be enabled with a simple jumper. SSFM spreads the switching frequency to fsw ±15% for reduced EMI.
