AX3022 Datasheet PDF

AXElite AX3022

The AX3022 series are monolithic IC designed for a step-down DC/DC converter, and own the ability of driving a 1.5A load without additional transistor. The external shutdown function can 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.

GENERAL DESCRIPTION

It saves board space. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. If current limit function occurs and VFB is down below 0.5V, the switching frequency will be reduced. The AX3022 series operates at a switching frequency of 200KHz thus allow smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +3% tolerance on output voltage under specified input voltage and output load conditions, The chips are available in a standard SOT89-5L package. 

FEATURES

Output voltage: adjustable output version. Adjustable version output voltage range: 0.75V to 22V+3%. 200KHz fixed switching frequency. Voltage mode non-synchronous PWM control. Thermal-shutdown and current-limit protection. ON/OFF shutdown control input. Short Circuit Protect (SCP). Operating voltage can be up to 24V.
