Description

General part information

LT8390A Series

The LT8390A 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 600kHz to 2MHz fixed frequency operation, or internal 25% 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 LT8390A is ideal for voltage regulator, battery and supercapacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.The LT8390A provides input or output current monitor and power good flag. Fault protection is also provided to detect output short-circuit condition, during which the LT8390A retries, latches off, or keeps running.Max Switching FrequencyMax Output PowerLT8390650kHz450W+LT8390A2MHz50W+APPLICATIONSAutomotive, Industrial, Telecom SystemsHigh Frequency Battery-Powered System
