SPECIFICATIONS  
Data Sheet  
ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY  
4.5 V ≤ (VDD1 = VDDA) ≤ 5.5 V; VDD2 = VREG = VISO = 5.0 V; fSW = 500 kHz; all voltages are relative to their respective grounds; see the  
application schematic in Figure 48. All minimum/maximum specifications apply over the entire recommended operating range, unless  
otherwise noted. All typical specifications are at TA = 25°C, VDD1 = VDDA = 5.0 V, VDD2 = VREG = VISO = 5.0 V.
