General Description

The TD1466 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 TD1466 requires a minimal number of readily‐available

external components.

The TD1466 is available in a SOT23‐6 package.
