Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8391DJUFDM is a synchronous 4-switch buck-boost LED controller. The LT8391DJUFDM is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltages above, below, or equal to the output voltage. A proprietary peak buck-peak boost current mode control scheme allows adjustable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangular spread spectrum operation for reduced EMI, and seamless low noise transitions between operating regions with input voltages ranging from 4V to 60V. The LT8391DJUFDM is ideal for LED driver applications in the automotive, industrial, and battery sectors.
