The LTC®3522 combines a 400mA buck-boost DC/DC converter with a 200mA synchronous buck DC/DC converter in a tiny 3mm × 3mm package.

Dual High Efﬁciency DC/DC Converters: Buck-Boost (VOUT: 2.2V to 5.25V, IOUT: 400mA for VIN > 3V, VOUT = 3.3V) Buck (VOUT: 0.6V to VIN, IOUT: 200mA).
2.4V to 5.5V Input Voltage Range.
Pin Selectable Burst Mode® Operation.
25μA Total Quiescent Current for Both Converters in Burst Mode Operation.
Independent Power Good Indicator Outputs.
Integrated Soft-Start.
Thermal and Overcurrent Protection.
