 GENERAL DESCRIPTION
The AX3015 series are monolithic IC designed for a step down DC/DC converter, and own the ability of driving a 2A load without additional transistor. It saves board space. The external shutdown function c an be controlled by logic level and then come into standby mode. The internal compensation makes feedback control having good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temper ature op erating 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 When SCP happened and VEN/CT>0.5V, the driver can be auto restart that can prevent driver damage. The auto restart time set by outside capacitor. The chip is available in SOP-8L-EP package which features small size as exposed pad to reduce the junction-to-case resistance.
