TPS630250RNCR from TI is a 2A 4-switch buck-boost maintaining fixed 3.3V whether input is above or below 3.3V. Ideal for Li-Ion (2.7-4.2V) to 3.3V systems. 2.5MHz allows tiny inductors. 30uA quiescent in power-save mode.<\/p>\n

4 internal MOSFETs in H-bridge. VIN greater than VOUT: buck mode. VIN less than VOUT: boost mode. VIN approximately VOUT: seamless buck-boost transition. Fixed 3.3V eliminates feedback resistors.<\/p>\n
