EVAL-LT8374-AZ

EVAL-LT8374-AZ is a synchronous stepdown LED driver featuring the LT®8374. It drives up to 36V of LEDs at 1.2A when the EMIVIN terminal is between 42V and 57V. EVAL-LT8374-AZ runs at 330KHz switching frequency and features options for spread-spectrum frequency modulation or external synchronization. The LT8374 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 is fixed at 330KHz, and the device can be synchronized with an external clock source or configured with internal SSFM for low EMI. With SSFM enabled, the LT8374 modulates its switching frequency between 330KHz and 410KHz to reduce switching emissions. EVALLT8374-AZ includes a SYNC/SSFM jumper to configure the LT8374 for either external synchronization, SSFM, or set to normal operation. The LT8374 can be analogue dimmed by applying a DC voltage between 1.25V and 250mV to the CTRL pin.

• Overvoltage protection (OVP)
• Features optional internal compensation options for reduced component-count designs
