EC1466 -60V, 800mA, 480kHz Non-synchronous Buck Converter

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.
