UD05104 Overview
The UTC UD05104 is a 1A high frequency synchronous Step Down DC/DC converter using constant frequency, current mode architecture. The device integrates main switch and synchronous rectifier switch for high efficiency without an external schottky diode. To maximize light load efficiency, The UTC UD05104 draws only 30μA quiescent current to improve light load efficiency.
