LT8355-1: 60VIN/120VOUT Dual LED Controller with Exponential PWM and Scalable Dimming
The LT8355-1 is a multitopology DC-to-DC controller designed to drive two strings of high-current LEDs with independent dual channels that support LED strings up to 120V. This product has an external PWM dimming ratio of 20,000:1 and an exponential internal control for a smooth change in brightness over the dimming range, creating an optimal human eye perception experience.
Key Features and Benefits
- Independent dual channels support high voltage LED strings up to 120V
- 128:1 internal exponential PWM dimming delivers uniform and stable dimming without using external microcontrollers or software
- 20,000:1 external dimming ratio for extreme ambient light conditions
Applications
- Automotive: Head lamps, tail lamps, heads-up displays (HUD), AEC-Q100 qualified
- Aerospace and Defense: Heads-up displays (HUD)
- Building and Infrastructure: Industrial lighting, high voltage LED
Evaluation Board
The LT8355-1 can be evaluated with the EVAL-LT8355-1-AZ.
