Regulators go high and low in one

Synchronous buck-boost convertor combines with synchronous buck regulator for powering processor applications that require both a 3.3V I/O rail and a 0.6 to 1.8V rail for the core voltage.

The LTC3522 is a dual-channel 1MHz synchronous convertor from Linear Technology One channel uses a synchronous buck-boost topology that can deliver up to 400mA of continuous output current with inputs above, equal, or below the output
