AX3055-Wide input Range CC/CV Step-down Converter DataSheet AEC-Q100
TheAX3055isa step down PWM converterwith a driving dual output current to4.8A.It is designed to allow for operating a wide supply voltage range from8V to 40V. Theexternal shutdown function can be controlled by logic level to pull COMPpin down, and thencomes into standby mode. The external compensation makes feedback control have goodline and load regulation with flexible external design.
TheAX3055operates in the CC (Constant outputCurrent) mode or CV (Constantoutput Voltage) mode, and the OCP current value is set by current sensing resisters.
TheAX3055is suitable for the DC/DC switching power applications when requestedthe current limit function. The devices are available inQFN5*5-20Lpackageand require
very few external devices for operation.
