Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8391IUFD is a synchronous 4-switch buck-boost LED controller. LED current can be regulated from an input voltage above, below, or equal to the output voltage. A proprietary peak buck-peak boost current mode control scheme allows adjustable and synchronised 150kHz to 650kHz fixed frequency operation, or internal ±15% triangular spread spectrum operation for reduced EMI, with 4V to 60V input, 0V to 60V output, and seamless low noise transitions between operating regions.
