IR3883 Description
The IR3883 SupIRBuck® is an easy-to-use, fully integrated and highly efficient monolithic DC/DC regulator. The on-chip PWM controller and MOSFETs make IR3883 a space-efficient solution, providing accurate power delivery. The IR3883 employs an Enhanced Stability (EaSy) engine that makes it stable with ceramic capacitors without pensation.
