***log Devices: The LT8391 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 4V to 60V input, 0V to 60V output, and seamless low noise transitions between operation regions, the LT8391 is ideal for LED driver and battery charger applications in automotive, industrial, and battery-powered systems. The LT8391 provides both internal (up to 128:1) and external (up to 2000:1) LED current PWM dimming with a high-side PMOS switch. Two CTRL pins provide flexible 20:1 analog dimming with ±3% LED current accuracy at 100mV full scale. Fault protection is provided to detect an open or short LED condition, during which the LT8391 retries, latches off, or keeps running. Switching Frequency Max Output Power LT8391 Adjustable 150kHz - 650kHz 450W+ LT8391A 2MHz 50W+ Applications Automotive Head Lamps/Running Lamps High Power LED Lighting

Optical ADI SLP

LT8391 Synchronous Buck-Boost LED Controllers: Linear Technology/Analog Devices LT8391 Controllers are 4-switch synchronous, buck-boost LED controllers. The controllers regulate output voltage, input or output current from an input voltage above, below, or equal to the output voltage. The peak-buck/peak-boost current mode control scheme enables adjustable and synchronizable 150kHz to 650kHz fixed frequency operation. The control scheme also allows internal ±15% triangle spread spectrum frequency modulation for low EMI. The LT8391 Controllers offer 4V to 60V input, 0V to 60V output voltage capability, and seamless low-noise transitions between operation regions The controllers are ideal for LED driver and battery and charger applications in automotive, industrial, telecom, and even battery-powered systems.Learn More
