Change 100V SMPS to Global Mains SMPS
Old SMPS:
100V only
TW brand controller
No load standby power = 0.7W
Light load (LinkStation standby = 1.3W)
Efficiency > 75%
46'C during full load
DIY the SMPS using
Infineon ICE3B2065 SMPS controller.
0.1W no load standby power
0.7W standby power with LinkStation
Schottky diode for lower loss and temperature.
Rubycon MBZ capacitor
Efficiency > 85%
37'C during full load
This kind of IC is very best for modification in DVD machine such as Denon DVD-29X0 series. Due to lower EMC, lower switching loss, and higher efficiency.
If using in $300-$1000 DVD machine, the effect is more significant.
