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.
