LT3790HFE#PBF

开关稳压器 60V Sync 4-Switch Buck-Boost Cntr

The is a 4-switch synchronous buck-boost voltage/current Regulator Controller for use with high-power battery-powered system. 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 200 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 provides input current monitor, output current monitor and various status flags, such as C/10 charge termination and shorted output flag.
