LTC3530EDD | Low VIN, 600mA Buck-Boost Converter

Product Details

Demonstration circuit 938 is a micropower synchronous buck-boost converter based on the LTC3530 monolithic buck-boost regulator. The DC938 has an input voltage range of 1.8 V to 5.5V and an output of 3.3V @ 500mA. The converter can work under manual or programmable automatic burst mode, providing high conversion efficiency over a wide range of load currents. The LTC3530 comes in a 10 lead 3×3 DFN package. These features make the DC938 demo board an ideal circuit for use in Li-Ion and dual cell AA (Alkaline/NiCad/NiMH) battery-powered, handheld applications.
