Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8391AIUFD controller is a 4-switch, synchronous buck-boost controller. The controller can regulate the output voltage, input or output current at input voltages above, below or equal to the output voltage. Using the peak-buck/peak-boost current mode control scheme, adjustable and synchronisable fixed frequency operation from 150kHz to 650kHz can be achieved. The control scheme also supports internal ±15% delta spread spectrum modulation for low EMI.
