OUTROS PART NUMBERS PARA ESTE COMPONENTE: BAA8WD THE SY8286A DEVELOPS A HIGH EFFICIENCY SYNCHRONOUS STEP-DOWN DC-DC REGULATOR CAPABLE OF DELIVERING 6A CURRENT. THE DEVICE INTEGRATES MAIN SWITCH AND SYNCHRONOUS SWITCH WITH VERY LOW RDS(ON) TO MINIMIZE THE CONDUCTION LOSS. THE SY8286A OPERATES OVER A WIDE INPUT VOLTAGE RANGE FROM 4V TO 23V. THE DC-DC REGULATOR ADOPTS THE INSTANT PWM ARCHITECTURE TO ACHIEVE FAST TRANSIENT RESPONSES FOR HIGH STEP DOWN APPLICATIONS AND HIGH EFFICIENCY AT LIGHT LOAD. THE DEVICE PROVIDES VARIOUS PROTECTION FEATURES FOR RELIABLE OPERATION. IN ADDITION, IT OPERATES AT PSEUDOCONSTANT FREQUENCY OF 600KHZ TO MINIMIZE THE SIZE OF INDUCTOR AND CAPACITOR. FEATURES LOW RDS(ON) FOR INTERNAL SWITCHES (TOP/BOTTOM): 38/19 M WIDE INPUT VOLTAGE RANGE: 4-23V INSTANT PWM ARCHITECTURE TO ACHIEVE FAST TRANSIENT RESPONSES INTERNAL 1.3MS SOFT-START LIMITS THE INRUSH CURRENT PSEUDO-CONSTANT FREQUENCY: 600KHZ. 6A OUTPUT CURRENT CAPABILITY /-1% INTERNAL REFERENCE VOLTAGE PFM/PWM SELECTABLE LIGHT L AD PERATION MODE OPTIONAL BYPASS INPUT POWER GOOD INDICATOR OUTPUT DISCHARGE OUTPUT CURRENT LIMIT PROTECTION HICCUP MODE OUTPUT SHORT CIRCUIT PROTECTION OUTPUT OVER VOLTAGE PROTECTION INPUT UVLO OV R T MPERATURE PROTECTION WITH AUTO RECOVERY ROHS COMPLIANT AND HALOGEN FREE COMPACT PACKAGE: QFN3X3-20 APPLICATIONS LCD-TV/NET-TV/3DTV SET TOP BOX NOTEBOOK HIGH POWER AP SY8286RAC CI PWM DC/DC DE 4 A 23V 6A QFN3X3-20 TAGS DE SY8286RAC: BAA8WD, SY8286RAC, SY8286B, SY8288RAC, SY8284RAC, SY8286, BAAXXX, BAA5XA, BAA4DE, BAA6FR, HIGH EFFICIENCY FAST RESPONSE 6A 23V INPUT SYNCHRONOUS STEP DOWN REGULATOR, CI PWM QFN 20, STEP-DOWN DC-DC REGULATOR
