Function • High efficiency. • Time-base generator (160kHz) incorporated. • Current limiter incorporated. • Thermal shutdown circuit incorporated. • Soft start circuit incorporated. Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum Input voltage VIN max 30 V Maximum Output current IO max 3 A SW pin application reverse voltage VSW -1 V Allowable power dissipation Pd max Mounted on a substrate.* 3.9 W VOS pin application reverse voltage VVOS -0.2 to +7 V Operating temperature Topr -30 to +125 °C Storage temperature Tstg -40 to +150 °C * Specified substrate : 76.1×114.3×1.6mm 3 : Copper foil ratio 60% FR4 Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Recommended Operating Conditions at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Input voltage range VIN 4.5 to 28 V Ordering number : ENA2191 Monolithic Linear IC Separately-excited Step-down Switching Regulator (Variable Type) Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
