... Philips Semiconductors High efficiency DC/DC converter External component selection I NDUCTOR The performance of the TEA1206 is not very sensitive to inductance value. Best efficiency performance over a wide load current range is achieved by using e.g. TDK SLF7032-6R8M1R6, having an inductance of 6.8 H and a saturation current level of 1 case the maximum output current is lower, other inductors are also suitable like the small sized Coilcraft DT1608 range ...
