Especificações Técnicas

OUTROS NUMEROS DE PEÇA PARA ESTE COMPONENTE: RT8813, 4E=5E THE RT8813D IS A 3/2/1 PHASE SYNCHRONOUS BUCK PWM CONTROLLER WHICH IS OPTIMIZED FOR HIGH PERFORMANCE GRAPHIC MICROPROCESSOR AND COMPUTER APPLICATIONS. THE IC INTEGRATES A CONSTANT-ON-TIME (COT) PWM CONTROLLER, TWO MOSFET DRIVERS WITH INTERNAL BOOTSTRAP DIODES, AS WELL AS CHANNEL CURRENT BALANCE AND PROTECTION S INCLUDING OVER VOLTAGE PROTECTION (OVP), UNDER VOLTAGE PROTECTION (UVP), CURRENT LIMIT, AND THERMAL SHUTDOWN INTO THE WQFN-24L 4X4 PACKAGE. THE RT8813D ADOPTS RDS(ON) CURRENT SENSING TECHNIQUE. CURRENT LIMIT IS ACCOMPLISHED THROUGH CONTINUOUS INDUCTORCURRENT-SENSE, RDS(ON) CURRENT SENSING IS USED FOR ACCURATE CHANNEL CURRENT BALANCE. USING THE METHOD OF CURRENT SAMPLING UTILIZES THE BEST ADVANTAGES OF EACH TECHNIQUE.   THE RT8813D FEATURES EXTERNAL REFERENCE INPUT AND PWMVID DYNAMIC OUTPUT VOLTAGE CONTROL, IN WHICH THE FEEDBACK VOLTAGE IS REGULATED AND TRACKS EXTERNAL INPUT REFERENCE VOLTAGE. OTHER FEATURES INCLUDE ADJUSTABLE SWITCHING FREQUENCY, DYNAMIC PHASE NUMBER CONTROL, INTERNAL SOFTSTART, POWER GOOD INDICATOR, AND ENABLE S.     FEATURES - MULTI-PHASE PWM CONTROLLER - TWO EMBEDDED MOSFET DRIVERS AND EMBEDDED SWITCHING BOOT DIODE - EXTERNAL REFERENCE INPUT CONTROL - PWM-VID DYNAMIC VOLTAGE CONTROL - DYNAMIC PHASE NUMBER CONTROL - LOSSLESS RDS(ON) CURRENT SENSING FOR CURRENT BALANCE - ADJUSTABLE CURRENT LIMIT THRESHOLD - ADJUSTABLE SWITCHING FREQUENCY - UVP/OVP PROTECTION - SHOOT THROUGH PROTECTION AND SHORT PULSE FREE TECHNOLOGY - SUPPORT AN ULTRA-LOW OUTPUT VOLTAGE AS STANDBY VOLTAGE - THERMAL ALERT INDICATOR IN 2/1 ACTIVE PHASE APPLICATION - THERMAL SHUTDOWN - POWER GOOD INDICATOR - ROHS COMPLIANT AND HALOGEN FREE APPLICATIONS - CPU/GPU CORE POWER SUPPLY - NOTEBOOK PC MEMORY POWER SUPPLY - CHIPSET/RAM POWER SUPPLY - GENERIC DC-DC POWER REGULATOR RT8813DGQW MULTI PHASE PWM CONTROLLER WITH PWM VID REFERENCE MAIORES DETALHES DE RT8813DGQW NO SITE DO FABRICANTE: HTTPS://DATASHEET.LCSC.COM/LCSC/1912111437_RICHTEK-TECH-RT8813DGQW_C426482.PDF TAGS DE RT8813DGQW: RT8813DGQW, RT8813, RT8813D, CI 4E=5E, 4E=5E, CI 4E, IC 4E
