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.
