IR3894 Synchronous Buck Regulator
12V Single Supply

The IR3894 SupIRBuckTM is an easy‐to‐use, fully integrated and highly efficient DC/DC
regulator. The onboard PWM controller and MOSFETs make IR3894 a space‐efficient
solution, providing accurate power delivery.

IR3894 is a versatile regulator which offers programmable switching frequency and the
fixed internal current limit The switching frequency is programmable from 300 kHz
to 1.5MHz for an optimum solution.

It also features important protection functions, such as Pre‐Bias startup, thermally
compensated current limit over voltage protection and thermal shutdown to give
required system level security in the event of fault conditions.
