Description
Product Overview
DC2345A demonstration circuit is a 60V synchronous 4-switch buck-boost LED controller with spread spectrum featuring the LT®8391 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. The LT8391 has a wide input voltage range down to 4V and up to 60V. It has adjustable switching frequency between 150KHz and 600KHz. There is a simple jumper option for external frequency synchronization, spread spectrum frequency modulation or neither. The LT8391 can be PWM dimmed with an external PWM signal and an internally generated PWM signal.
