DC527A - LT3433EFE | Step-Up/Step-Down Converter, 4V to 60V Input, Vout=5V/400mA @ 12Vin, See Load Current Table

Demonstration circuit 527 is a monolithic step-up / stepdown DC/DC switching converter with Burst Mode™ featuring the LT3433. The board is optimized for 5V output at up to 400mA load current (12VIN) and an input voltage range of 4V to 60V. The demo board is also useful for buck-only needs and can provide 5V@340mA from a 48V input and 5V@400mA from a 12V input.
