AX3016
1.2A PWM Buck DC/DC Converter
GENERAL DESCRIPTION
The AX3016/A series are monolithic IC designed for a step-down DC/DC converter,
and own the ability of driving a 1.2A load without additional transistor. It saves board space.
The external shutdown function can be controlled by logic level and then come into standby
mode. The outside compensation makes feedback control having good line and load
regulation. Regarding protected function, thermal shutdown is to prevent over temperature
operating from damage; current limit is against over current operating of the output switch
that set by outside resistance. Current limit depends on RSENSE value. The over voltage
protection (OVP) that can avoid high VOUT voltage to damage circuit and capacitor, the
OVP voltage is set by outside resistances. The chip is available in SOP-8L-EP package
which features small size as exposed pad to reduce the junction-to-case resistance.
