LTC3130 Single-Cell 1.2V, 200mA Buck-Boost Converter

Figure 17. Single-Cell 1.2V, 2l]0mA Buck Boost Converter, Using the LTC3525-3.3 to Provide the EXTVcc Bias Supply

The LTC3130/LTC3130-1 are high efficiency, low noise, 600mA buck-boost converters with wide VIN and VOUT ranges. For high efficiency operation at light loads, BurstMode operation can be selected, reducing the quiescent current to just 1.6µA. Converter start-up is achieved from sources as low as 7.5µW.
