Product Details

Demonstration circuit 700 is a 2.4MHz, Dual Phase Step-Up DC/DC Converter featuring the LTC3428EDD. The demo board demonstrates a dual phase DC/DC boost converter, with a 2A switch (per phase), capable of providing either 5V at 2A or 3.3V at 1.5A. The circuit demonstrates the advantages of the dual phase architecture for an effective switching frequency of 2.4MHz.
