Features - - - - - - - - - - - - - - - - 6A HIGHLY INTEGRATED WIDE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR Description The IR3863 Sup IRBuck TM 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 pensated 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 21V Output Voltage Range: 0.5V to 12V Continuous 6A Load Capability Constant On-Time Control pensation Loop not Required Excellent Efficiency at Very Low Output Currents Programmable Switching Frequency and Soft Start Thermally pensated 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 Applications - - - - Notebook and Desktop puters Game Consoles Consumer Electronics - STB, LCD, TV, Printers General Purpose POL DC-DC Converters 8/8/2012 Rev3.2 Free Datasheet http://../ ABSOLUTE MAXIMUM RATINGS (Voltages referenced to GND unless otherwise specified) - - - - - - - - - - - - VIN, FF …………………………………………………. -0.3V to 25V VCC, PGOOD, EN ………………………………… -0.3V to 8.0V BOOT …………………………………………………… -0.3V to 33V PHASE …………………………………………………. -0.3V to 25V(DC), -5V(100ns) BOOT to PHASE ………………………………………. -0.3V to 8V ISET …………………………………………………….. -0.3V to 25V, 30m A PGND to GND …………………………………………. -0.3V to +0.3V All other pins...
