TD1466  _{60V, 800MA, 480kHz Non-synchronous Buck Converter}

(DATASHEET)

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.
