1 / 21 page 1 PD-97605 IR3863MPBF 8/8/2012 Rev3.2 1 Applications Notebook and Desktop Computers Game Consoles Consumer Electronics – STB, LCD, TV, Printers General Purpose POL DC-DC Converters Description The IR3863 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 IR3863 a space-efficient solution that delivers up to 6A of precisely controlled output voltage. Programmable switching frequency, soft start, and thermally compensated 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. 6A HIGHLY INTEGRATED WIDE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR SupIRBuckTM Features Input Voltage Range: 3V to 21V Output Voltage Range: 0.5V to 12V Continuous 6A Load Capability Constant On-Time Control Compensation Loop not Required Excellent Efficiency at Very Low Output Currents Programmable Switching Frequency and Soft Start Thermally Compensated Over Current Protection Power Good Output Precision Voltage Reference (0.5V, +/-1%) Enable Input with Voltage Monitoring Capability Pre-bias Start Up Thermal Shut Down Under/Over Voltage Fault Protection Forced Continuous Conduction Mode Option Very Small, Low Profile 4mm x 5mm QFN Package |
