The DC2834A supports two ways of biasing the controller. The first is directly from the input voltage or output rail through EXTVCC. The second is connecting an external voltage source to the EXTVCC terminal.
The DC2834A supports an extremely wide 100kHz to 3MHz switching frequency range. Spread spectrum operation reduces the peak radiated and conducted noise to simplify compliance with electromagnetic interference (EMI) standards.
The DC2834A has a small circuit footprint, is a high performance and high-density solution for telecom, automotive, and Power over Ethernet applications.
