OUTROS PART NUMBERS PARA ESTE COMPONENTE: NB681GD-Z, AKVF, AKVE, AKVG, AKV THE NB681 IS A FULLY INTEGRATED, HIGHFREQUENCY, SYNCHRONOUS, RECTIFIED, STEPDOWN, SWITCHMODE CONVERTER WITH 2BIT VID, ESPECIALLY DESIGNED FOR IMVP8 APPLICATIONSVCCIO, PRIMCORE, V1.0A, EDRAM, AND EOPIO. IT OFFERS A VERY COMPACT SOLUTION TO ACHIEVE A 6A CONTINUOUS OUTPUT CURRENT AND A 7.5A PEAK OUTPUT CURRENT OVER A WIDE INPUT SUPPLY RANGE. THE NB681 OPERATES AT HIGH EFFICIENCY OVER A WIDE OUTPUT CURRENT LOAD RANGE BASED ON MPS PROPRIETARY SWITCHING LOSS REDUCTION TECHNOLOGY AND INTERNAL LOW RON POWER MOSFETS. ADAPTIVE CONSTANTONTIME (COT) CONTROL MODE PROVIDES FAST TRANSIENT RESPONSE AND EASES LOOP STABILIZATION. THE DC AUTOTUNE LOOP PROVIDES GOOD LOAD AND LINE REGULATION. TO AVOID AUDIBLE NOISE, NB681 PROVIDES LOWPOWER MODE FOR POWER LOSS SAVING DURING THE LOWPOWER STATE AND ULTRASONIC MODE. FULL PROTECTION FEATURES INCLUDE OC LIMIT, OVP, UVP, AND THERMAL SHUTDOWN. THE CONVERTER REQUIRES A MINIMAL NUMBER OF EXTERNAL COMPONENTS, AND IT IS AVAILABLE IN A QFN 2MM X 3 MM PACKAGE.   KEY FEATURES WIDE 4.5V TO 26V OPERATING INPUT RANGE VCCIO/PRIMCORE/EDRAM/EOPIO/V1.0A COMPATIBLE FOR IMVP8 OUTPUT ADJUSTABLE BY 2BIT VID LOWPOWER MODE 25A LOW QUIESCENT CURRENT 6A CONTINOUS OUTPUT CURRENT 7.5A PEAK OUTPUT CURRENT SELECTABLE ULTRASONIC MODE ADAPTIVE COT FOR FAST TRANSIENT DC AUTOTUNE LOOP STABLE WITH POSCAP AND CERAMIC CAPACITORS 1% REFERENCE VOLTAGE INTERNAL SOFT START OUTPUT DISCHARGE OCL, OVP, UVP, AND THERMAL SHUTDOWN, LATCHOFF RESET VIA EN OR POWER CYCLE QFN 2MM X 3MM PACKAGE.   MANUFACTURER: MONOLITHIC POWER SYSTEMS (MPS) PRODUCT CATEGORY: SWITCHING VOLTAGE REGULATORS     MOUNTING STYLE: SMD/SMT PACKAGE / CASE: QFN13 TOPOLOGY: BUCK OUTPUT VOLTAGE: 0V TO 1.2V OUTPUT CURRENT: 6 A NUMBER OF OUTPUTS: 1 OUTPUT INPUT VOLTAGE, MIN: 4.5V INPUT VOLTAGE, MAX: 26V SWITCHING FREQUENCY: 750 KHZ SERIES: NB681 PACKAGING: REEL BRAND: MONOLITHIC POWER SYSTEMS (MPS) INPUT VOLTAGE: 4.5V TO 26V OPERATING SUPPLY CURRENT: 25UA PRODUCT: VOLTAGE REGULATORS PRODUCT TYPE: SWITCHING VOLTAGE REGULATORS SHUTDOWN: SHUTDOWN     FEATURES E BENEFITS WIDE 4.5 V TO 26 V OPERATING INPUT RANGE VCCIO/PRIMCORE/EDRAM/EOPIO/V1.0A COMPATIBLE FOR IMVP8 OUTPUT ADJUSTABLE BY 2BIT VID LOWPOWER MODE 25 A LOW QUIESCENT CURRENT 6 A CONTINOUS OUTPUT CURRENT 7.5 A PEAK OUTPUT CURRENT SELECTABLE ULTRASONIC MODE ADAPTIVE COT FOR FAST TRANSIENT DC AUTOTUNE LOOP STABLE WITH POSCAP AND CERAMIC CAPACITORS 1% REFERENCE VOLTAGE INTERNAL SOFT START OUTPUT DISCHARGE OCL, OVP, UVP, AND THERMAL SHUTDOWN, LATCHOFF RESET VIA EN OR POWER CYCLE QFN 2MM X 3MM PACKAGE NB681 DC-DC SINGLE STEP DOWN 4.5V TO 26V 13PIN QFN13 MAIORES DETALHES DE NB681 NO SITE DO FABRICANTE: HTTPS://WWW.MONOLITHICPOWER.COM/EN/DOCUMENTVIEW/PRODUCTDOCUMENT/INDEX/VERSION/2/ TAGS DE NB681: NB681, NB681GD, NB681GDZ, CI AKVF, CI AKVE, CI AKVG, CI AKV
