d2 Blu-ray & DVD +/- RW v.1 Lacie power supply specifications, info and reviews for d2 Blu-ray & DVD +/- RW v.1. Lacie is well known for their External hard drives, external, raid and network hard drive and therefore sometimes we need to buy a power supply.
The compact 5 pin L165 IC general a stabilized symmetrical power supply from a single asymmetrical power supply. The output voltage is however, half of the input voltage. One needs to add the ripple filter capacitors C1, C2, C3 and C4 and some resistors for setting the symmetry. In constructing the circuit, place the capacitors C1 and C2 as close to the IC as possible.
