Description

General part information

LT3790 Series

The LT3790 is a synchronous 4-switch buck-boost voltage/current regulator controller. The LT3790 can regulate output voltage, output current, or input current with input voltages above, below, or equal to the output voltage. The constant-frequency, current mode architecture allows its frequency to be adjusted or synchronized from 200kHz to 700kHz. No top FET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions, the LT3790 is ideal for voltage regulator, battery/super-capacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.The LT3790 provides input current monitor, output current monitor, and various status flags, such as C/10 charge termination and shorted output flag.APPLICATIONSAutomotive, Telecom, Industrial SystemsHigh Power Battery-Powered System
