DC878A - LTC3458LEDE Demo Board | 2V ≤ VIN ≤ 5V, Vout = 5V @ 300mA - 900mA

Demonstration circuit 878 is a 1MHz Synchronous Step-Up DC/DC Converter featuring the LTC®3458LEDE. The demo board demonstrates a DC/DC boost converter, with a 1.7A switch, providing 5V at 300mA to 900mA depending on input voltage, which ranges from 2V to 5V.

The circuit demonstrates the advantages of output disconnect and inrush current limiting.
