Analog Devices Inc. EVAL-LT8376-AZ Evaluation Board features the LT8376 LED Driver. The LT8376 60V, 3A Synchronous Step-Down LED Driver is a monolithic DC/DC converter featuring fixed-frequency, peak current control, and PWM dimming for a string of LEDs.
The ADI EVAL-LT8376-AZ Evaluation Board drives a single string of LEDs up to 36V at 1.5A when VIN is between 43V and 57V. The EVAL-LT8376-AZ supports an undervoltage lockout (UVLO) set at 40V with 2V hysteresis for turn-on. The EVAL-LT8376-AZ runs at 350kHz switching frequency and offers optional spread spectrum modulation (SSFM). Additionally, with SSFM enabled, the LT8376 modulates its switching frequency from fSW to fSW + 25% to reduce EMI emissions.
