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 AX3007A series operates at a switching frequency of 85KHz thus allow smaller sized filter components than what would be needed with lower frequency switching regulators. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The chips are available in standard SOP-8L, SOP-8L-EP and TO252-5L packages. FEATURES
Output voltage: 3.3V, 5V, 12V and adjustable output version. Adjustable version output voltage range, 1.23V to 38.5V. 85KHz 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 40V. Output load current: 2A.
