LTC3130/LTC3130-1  
25V, 600mA Buck-Boost  
DC/DC Converter with  
1.6µA Quiescent Current  
FEATURES  
DESCRIPTION  
The LTC3130/LTC3130-1 are high efficiency, low noise,  
600mA buck-boost converters with wide V and V  
ranges. For high efficiency operation at light loads,  
BurstModeoperationcanbeselected, reducingthequies-  
cent current to just 1.6µA. Converter start-up is achieved  
from sources as low as 7.5µW.

TheLTC3130/LTC3130-1employanultralownoise,1.2MHz  
PWM architecture that minimizes solution footprint by  
allowing the use of tiny, low profile inductors and ceramic  
capacitors. Built-in loop compensation and soft-start  
reduces external parts count and simplifies the design.  
FeaturesincludeanaccurateRUNcomparator thresholdto  
allow predictable regulator turn-on and a maximum power  
point control (MPPC) capability that ensures maximum  
power extraction from non-ideal sources such as photo-  
voltaic panels. The LTC3130-1 includes an internal voltage  
divider to provide four selectable fixed output voltages.
