Line and load regulation are measured at a constant junction temperature using a low duty cycle pulse technique. Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 26W. Power dissipation is determined by the input/output differential voltage and output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range. 2. Guaranteed by design, characterization or correlation to other tested parameters. 3. Specifications apply over the operating temperature range. 2 www.irf.com OM7671NM Load Regulation Short Circuit Current Fig 1: Typical Minimum Output Differential Vs Output Current Fig 2: Typical Short Circuit Current Vs Input/Output Differential Dropout Voltage Fig 3: Typical Output Voltage Deviation Vs Temperature www.irf.com 3 OM7671NM Case Outline and Dimensions - SMD-1 PAD ASSIGNMENTS Pin 1 - Vout Pin 2 - Ground Pin 3 - Vin Part Numbering Nomenclature OM 7671 Device Number N M Package Code M = SMD-1 Isolated / Non-Isolated N = Non-Isolated IR WORLD HEADQUARTERS: 233 Kansas St., El Segundo, California 90245, USA Tel: (310) 252-7105 IR LEOMINSTER : 205 Crawford St., Leominster, Massachusetts 01453, USA Tel: (978) 534-5776 Data and specifications subject to change without notice. 07/2007 4 www.irf.com
