LTC3130 3.3V Converter with "Last Gasp" Hold-Up, Runs Storage Capacitor Down to 0.9V

Figure 14. 3.3V converter with "Last Gasp" Hold-Up, Runs Storage capacitor Down to 0.9V

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.
