Analog Devices LT8374-1 | Demoboard EVAL-LT8374-1

Description

Evaluation board EVAL-LT8374-1-AZ is a synchronous step-down LED driver featuring the LT8374-1. It drives up to 15V of LEDs at 1A when the EMIVIN terminal is between 18V and 47V. EVAL-LT8374-1-AZ runs at 2MHz switching frequency and features options for spread-spectrum frequency modulation (SSFM) or external synchronization.The LT8374-1 has an input voltage range of 6.5V to 60V. It features 60V synchronous internal power switches for high efficiency and small solution size. The switching frequency of LT8374-1 is fixed at 2MHz, and the device can be synchronized with an external clock source or configured with internal SSFM for low EMI. With SSFM enabled, the LT8374-1 modulates its switching frequency between 2MHz and 2.5MHz to reduce switching emissions. EVAL-LT8374-1-AZ includes a SYNC/SSFM jumper to configure the LT8374-1 for either external synchronization, SSFM, or set to normal operation.
