IR3898 Synchronous Buck Regulator
12V Single Supply

The IR3898 SupIRBuck® is an easy‐to‐use, fully integrated and highly efficient DC/DC
regulator. The onboard PWM controller and MOSFETs make IR3898 a space‐efficient
solution, providing accurate power delivery.

IR3898 is a versatile regulator which offers programmable switching frequency and the
fixed internal current limit while operates in wide input and output voltage range.

The switching frequency is programmable from 300kHz 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.
