AX3050/A

Output Over-Voltage protection

The AX3050/A provides output over-voltage protection function. When output

over-voltage happens (VSENS2> 5.8V), the AX3050/A shuts down. When output

over-voltage is released (VSENS2< 5.7V), the AX3050/A recovers to normal state

automatically.

Output Short-Circuit protection

The AX3050/A provides output short-circuit protection function. When VOUT is short

(VFB<0.4V), the auto restart function can be started that restart the regulator cycle by cycle.

The cycle time is set by internal counter.

The AX3050/A disables switching when its junction temperature exceeds 140°C and

resumes when the temperature has dropped by 30°C.
