Overview

AT2003 Wide Input sensorless CC/CV 2A Buck Converter General Description AT2003 is a wide input voltage, high efficiency stepdown DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.
AT2003 provides up to 3A output current at 120kHz switching frequency ,and the CC level can be adjusted by changing external sensing resister.
The AT2003 provides full protection functions, thermal shutdown is to prevent over temperature operating from damage; cycle by cycle current limit is against over current operating of the switch; and over voltage protection (OVP) that can avoid high Vout voltage to damage circuit and capacitor.
The devices is av...
