LT8390IUFD#PBF General Description

The LT8390 is a synchronous 4-switch buck-boost DC/DC controller that regulates output voltage, input or output current from an 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 frequency modulation for low EMI. With a 4V to 60V input voltage range, 0V to 60V output voltage capability, and seamless low-noise transitions between operation regions, the LT8390 is ideal for voltage regulator, battery and supercapacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.

Key Features

  • 4-Switch Single Inductor Architecture Allows VIN Above, Below or Equal to VOUT
  • Synchronous Switching: Up to 98% Efficiency
  • Proprietary Peak-Buck Peak-Boost Current Mode
  • Wide VIN Range: 4V to 60V
  • ±1.5% Output Voltage Accuracy: 1V ≤ VOUT ≤ 60V
  • ±3% Input or Output Current Accuracy with Monitor
  • Spread Spectrum Frequency Modulation for Low EMI

Application

  • Automotive, Industrial, Telecom Systems
  • High Power Battery-Powered System
