The EUP3293 is a high frequency synchronous rectified step-down current mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range from 4.5V to 24V. The EUP3293 has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include input under voltage lockout,input over voltage protection, output under voltage protection, over-current protection and thermal shutdown.

The EUP3293 requires a minimal number of readilyavailable standard external components, and is available in a space-saving 8-pin TSOT23 package.
