Analog Devices LTC3130-1

Description

The LTC3130/LTC3130-1 are high efficiency, low noise,600mA buck-boost converters with wide VIN and VOUTranges. For high efficiency operation at light loads,Burst Mode operation can be selected, reducing the quiescentcurrent to just 1.6μA. Converter start-up is achievedfrom sources as low as 7.5μW.
