IR3812MPbF

The IR3812MPbF SupIRBuckTM is an easy-to-use, fullyintegrated and highly efficient DC/DC regulator.The onboard switching controller and MOSFETs make the IR3812 a space-efficient solution,providing accurate power delivery for low output voltage applications.
The IR3812MPbF operates from a 4.5V to 14V input supply and generates an output voltageadjustable from 0.6V to 0.80*Vin at loads up to 4A.IR3812 can be configured for trackingapplications to generate termination voltage (VTT)
for memory applications.
A versatile regulator offering programmability of start up time and current limit, the IR3812's fixed 600kHz switching frequency allows the use of small external components.
IR3812MPbF also features important protection functions, such as Pre-Bias startup, hiccup current limit and thermal shutdown to provide the required system level security in the event of fault conditions.
