DC999A - LTC3533EDE Demo Board | High Efficiency Synchronous Buck-Boost Converter

Demonstration circuit 999A is a wide input range, 3.3V, synchronous buck-boost converter featuring the LTC3533.  This circuit is designed to demonstrate the high level of performance, efficiency and small solution size attainable using this part in a buck-boost power supply. It operates at 1MHz and produces a regulated 3.3V from an input voltage range of 2.4V to 5.5V, and operates down to 1.8V with de-rated output current.
