This data was taken with the components listed below mounted on the printed circuit board shown in Figure 22.
* With MBR2535CTL, 79.8% efficiency. PCB layout modification is required to use this rectifier.
For high efficiency and small circuit board size, the Sanyo Os−Con capacitors are recommended for C8, C9, C10 and C11.
C8, C9, C10 = Sanyo Os−Con #6SA330M, 330 mF 6.3 V.
C11 = Sanyo Os−Con #10SA220M, 220 mF 10 V.
L1 = Coilcraft S5088−A, 5.0 mH, 0.11 W.
T1 = Coilcraft S5502−A
Primary: 77 turns of # 28 AWG, Pin 1 = start, Pin 8 = finish.
Two layers 0.002″ Mylar tape.
Secondary: 5 turns of # 22 AWG, 2 strands bifiliar wound, Pin 5 = start, Pin 4 = finish.
Two layers 0.002″ Mylar tape.
Auxiliary: 13 turns of # 28 AWG wound in center of bobbin, Pin 2 = start, Pin 7 = finish.
Two layers 0.002″ Mylar tape.
Gap: 0.006″ total for a primary inductance (LP) of 1.0 mH.
Core and Bobbin: Coilcraft PT1950, E187, 3F3 material.
