AT2003Z Wide Input sensorless CC/CV 2A Buck Converter
General Description
AT2003S is a wide input voltage, high efficiency stepdown DC/DC converter that operates in either CV (ConstantOutput Voltage) mode or CC (Constant OutputCurrent) mode.
AT2003S provides up to 3A output current at 120kHz switching frequency ,and the CC level can be
adjusted by changing external sensing resister.
The AT2003S 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 available in PSOP8-8L package and require very few external devices for operation.
