Analog Devices Inc. LT3790 4-Switch Buck-Boost Controllers are synchronous 4-switch buck-boost voltage/current regulator controllers. The LT3790 from Analog Devices 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.
4-switch single inductor architecture allows VIN above, below, or equal to VOUT
Up to 98.5% efficiency synchronous switching
4.7V to 60V wide VIN range
1.2V ≤ VOUT < 60V 2% output voltage accuracy
0V ≤ VOUT < 60V 6% output current accuracy
Input and output current regulation with current monitor outputs
