upgraded Linear power module for OPPO 103, 103D. 93 and 105, 105D , 95

 Upgraded Linear power module  for OPPO 103, 103D and 93

 

- Low ESR Nichicon Electroytic Audio grade capacitors

- All discrete Schottky Barrier diodes.

The Schottky diode (named after German physicist Walter H. Schottky) is a semiconductor diode with a low forward voltage drop and a very fast switching action.

When current flows through a diode there is a small voltage drop across the diode terminals. A normal silicon diode has a voltage drop between 0.6–0.7 volts, while a Schottky diode voltage drop is between approximately 0.15–0.45 volts. This lower voltage drop can provide higher switching speed and better system efficiency.

It produce much less heat and EMI and switching noise.

 But it is expensive and exist only discrete device. I used 8 or 12 Schottky diodes in this LPM

- 1 UF/63V  Wima Polyproplyne Film capacitor and 33 uF tantalium capacitors for  regualtor IC buffering/impedence matching.
