Company: Analog Devices
Category: Automotive Product of the Year
The LT8386 is a 60V, 3A Synchronous, Boost LED Driver with flexibility for analog or duty cycle LED current control. It provides up to 50,000:1 PWM Dimming for a string of LEDs of up to 52V , ideal for high contrast applications including automotive head-up displays. 512:1 Internal PWM Dimming provides accurate brightness control in headlight and taillight applications, and eliminates need for a microcontroller. The LT8386 features Analog Devices’ proprietary Silent Switcher technology to provide ultralow EMI with high efficiency, easily exceeding the CISPR 25 EMI standards. Tight LED current regulation ensures constant brightness of LEDs in side-by-side strings., imperceptible to a human eye Switching frequency operation up to 2MHz minimizes solution size and keeps switching noise above AM Band, while still maintaining high efficiency with the Silent Switcher architecture.
The device is AEC-Q100 qualified for Automotive Applications:
Instrument Panel lighting (HUD)
Flash/Machine Vision (IR Driver Status Monitor)
