General Description

The EC1466 is a monolithic, step‐ down, switch mode converter with a built‐ in power MOSFET. It achieves a
0.8A peak‐ output current over input supply 10V‐ 60V with excellent load and line regulation.

Current‐ mode operation provides a fast transient response and eases loop stabilization.

Fault condition protections include cycle‐ by‐ cycle current limiting and thermal shutdown.

The EC1466 requires a minimal number of readily‐available external components. The EC1466 is available in a SOT23‐ 6 package.
