Linear Technology/Analog Devices LT3790EFE#PBF 4-Switch Buck-Boost Controllers are synchronous 4-switch buck-boost voltage/current regulator controllers. The LT3790EFE#PBF can regulate output voltage/current, or input current with input voltages above, below, or equal to the output voltage. The constant-frequency, current mode architecture allows the controllers' frequency to be adjusted or synchronized from 200kHz to 700kHz.
