AX3071
Wide Input Range CC/CV Step Down
Controller
GENERAL DESCRIPTION
The AX3071 is a step down PWM controller with a driving dual output current to 4.8A.
It is designed to allow for operating a wide supply voltage range from 8V 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 AX307 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 AX3071 is suitable for the DC/DC switching power applications when requested
the current limit function. The devices are available in MSOP-10L packages and require very
few external devices for operation.
