Description
The LM2825 is a complete 1A DC-DC Buck converter packaged in a 24-lead molded Dual-In-Line integrated circuit package.
Contained within the package are all the active and passive components for a high efficiency step-down (buck) switching regulator. Available in fixed output voltages of 3.3V, 5V and 12V, as well as two adjustable versions, these devices can provide up to 1A of load current with fully guaranteed electrical specifications.
Self-contained, this converter is also fully protected from output fault conditions, such as excessive load current, short circuits, or excessive temperatures.

Applications
    Simple high-efficiency step-down (buck) regulator
    On-card switching regulators
    Efficient pre-regulator for linear regulators
    Distributed power systems
    DC/DC module replacement
