LT8356-1: 100 VIN / 120 VOUT LED Controller with Exponential PWM and Scalable Dimming
The LT8356-1 is a DC/DC controller designed to drive high current LEDs. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. A voltage feedback pin serves as the input for several LED protection features and makes it possible for the converter to operate as a constant-voltage source. The LT8356-1 can implement boost, buck-boost mode, buck-mode, SEPIC, and flyback LED drivers. This product is also AEC-Q100 qualified.
Key Features and Benefits:
- • Supports high voltage LED strings up to 120 V with SSFM to meet stringent automotive EMI standards
- • Internal exponential PWM dimming creates a smooth change in brightness over the complete dimming range without external microcontrollers
- • Internal two pin multiplied parabolic analog dimming helps match the exact brightness of two identical lamps
Applications:
- • Automotive: Automotive lamps
- • Industrial Automation
- • General Purpose: High voltage industrial lighting, airport runway, building, architectural lighting
