AX3070
Wide Input Range CC/CV Step Down
Controller
GENERAL DESCRIPTION
The AX3070 is a step down PWM controller with a driving dual output current to 4.8 A (2.4A+2.4A). It is designed to allow for operating a wide supply voltage range from 9V to 40V. The external shutdown function can be controlled by logic level to pull COMP/EN pin down, and then comes into standby mode. The external compensation makes feedback control have good line and load regulation with flexible external design.
The AX3070 operates in the CC (Constant output Current) mode or CV (Constant output Voltage) mode, and the OCP current value is set by current sensing resisters.
The AX3070 is suitable for the DC/DC switching power applications when requested the current limit function.
