800k Hz 3A Ea Sy Sup IRBuck® Synchronous Buck Regulator Rev 3.1, 09/07/2021 Power Management & Multimarket Product Overview IR3883 Sup IRBuck® Synchronous Buck Regulator Product Overview Features - Wide Input Voltage Range (2.5V-14V) with an external Vcc - Single Input Voltage Range (4.5V to 14V) - Continuous 3A Load Capability - 800k Hz Switching Frequency - 10u A Supply Current at Shutdown - Ea Sy Sup IRBuck® engine Stable with Ceramic Capacitors and no External pensation - Enhanced Light Load Efficiency with Reduced Switching Frequency and Diode Emulation - Forced Continuous Conduction Mode Option - Thermally pensated Peak Over-Current Protection with three selectable levels - Internal Soft-Start - Enable Input - Pre-bias Start Up - Thermal Shut Down - Power Good Output - Precision Reference Voltage (0.5V+/-0.6%) - Small Size 3mmx3mm QFN - Lead-free, Halogen-free and Ro HS6 pliant Description The IR3883 Sup IRBuck® 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 (Ea Sy) engine that makes it stable with ceramic capacitors without pensation. IR3883 can operate in Forced Continuous Conduction Mode (FCCM) or can enter Diode Emulation mode during light loads to save power. With ultra-light loads, IR3883 can enter a low quiescent current mode making it ideal for Standby power supplies. It Features important protection functions, such as Pre-bias startup, internal soft-start, hiccup overcurrent protection and thermal shutdown to give required system level security in the event of fault conditions.
