IR3871MPBF

PD-97472 IR3871MPBF SupIRBuck Features             TM 8A HIGHLY INTEGRATED WIDE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR Description The IR3871 SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC voltage regulator. The onboard constant on time hysteretic controller and MOSFETs make IR3871 a space-efficient solution that delivers up to 8A of precisely controlled output voltage in 60°C ambient temperature applications without airflow. Programmable switching frequency, soft start, and over current protection allows for a very flexible solution suitable for many different applications and an ideal choice for battery powered applications. Additional features include pre-bias startup, very precise 0.5V reference, over/under voltage shut down, power good output, and enable input with voltage monitoring capability. Input Voltage Range: 3V to 26V Output Voltage Range: 0.5V to 12V Continuous 8A Load Capability Constant On-Time control Excellent Efficiency at very low output current levels Compensation Loop not required Programmable switching frequency, soft start, and over current protection Power Good Output Precision Voltage Reference (0.5V, +/-1%) Pre-bias Start Up Under/Over Voltage Fault Protection Ultra small, low profile 5 x 6mm QFN Package Applications     Notebook and desktop computers Game consoles Consumer electronics – STB, LCD, TV, printers General purpose POL DC-DC converters 1 Free Datasheet http://www.datasheet4u.com/ IR38...
