Overview

The IR3897 SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard PWM controller and MOSFETs make IR3897 a space-efficient solution, providing accurate power delivery. IR3897 is a versatile regulator which offers programmability of switching frequency and 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.
