General Description

The TD1468 is a monolithic, step‐down, switch mode converter

with a built‐in power MOSFET. It achieves a 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 TD1468 requires a minimal number of readily‐available

external components.

The TD1468 is available in a ESOP‐8 package.
