Programmable Switching Frequency up to 1.5MHz  
Programmable Over Current Protection (Hiccup)  
PGood output  
IR3841 is a versatile regulator which offers  
programmability of start up time, switching  
frequency and current limit while operating in  
wide input and output voltage range.  
Precision Reference Voltage (0.7V, +/-1%)  
Programmable Soft-Start  
Enable Input with Voltage Monitoring Capability  
Enhanced Pre-Bias Start-up  
The switching frequency is programmable from  
250kHz to 1.5MHz for an optimum solution.  
Seq input for Tracking applications  
-40oC to 125oC operating junction temperature  
It also features important protection functions,  
such as Pre-Bias startup, hiccup current limit and  
thermal shutdown to give required system level  
security in the event of fault conditions.  
Thermal Protection  
Pin compatible option for 4A and 12A devices
