Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8390 is a synchronous 4-switch buck-boost DC/DC controller that regulates output voltage, input or output current according to input voltages above, below or equal to the output voltage. The proprietary peak-buck/peak-boost current mode control scheme supports adjustable and synchronisable 150kHz to 650kHz fixed frequency operation, or internal ±15% delta spread modulation for reduced EMI.

With a 4V to 60V input voltage range and 0V to 60V output voltage capability, and supporting seamless low noise transitions between operating regions, the LT8390 is ideal for regulator, battery and supercapacitor charger applications in automotive, industrial, telecom and battery powered systems.
