FET integrated in U1. An RCDZ (Zener bleed) clamp (VR1, C4, R5, D5) is used to give higher load efficiency and lower no-load consumption. The RCDZ clamp provides a tighter tolerance than a simple Zener clamp and allows a VOR as high as 150 V. The use of high VOR allows the use of 60 V Schottky diodes (D8, D9) instead of 80 V or 100 V types.
