IR3887MTRPBFAUMA1

IR3887MTRPBFAUMA1 is a 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. It employ an Enhanced Stability engine that makes it stable with ceramic capacitors without compensation. It can operate in Forced Continuous Conduction Mode or can enter Diode Emulation mode during light loads to save power. With ultra-light loads, it can enter a low quiescent current mode making it ideal for Standby power supplies. It features important protection functions, such as Pre-bias start-up, internal soft-start, hiccup overcurrent protection and thermal shutdown to give required system level security in the event of fault conditions. Application includes server and computing, storage applications, communications infrastructure, general DC-DC converters, distributed point of load power architectures.
