General Description
The EC1466 is a monolithic, step‐down, switch mode converter with a built‐in power MOSFET. It achieves a 1.2A 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.
