LTC3784 - Polyphase Boost #2 10

LTC3784 – 1200W Polyphase Boost Converter

Mit einem Eingangsspannungsbereich von 10-50V stehen ausgangsseitig 1200W bei 50V zur Verfügung wobei die maximal mögliche Dauerleistung von der Eingangsspannung sowie thermischen Anbindung limitiert wird. Der Wirkungsgrad bei 11V Eingangsspannung und 750W Ausgangslast ist besser 95%. Bei Abruf von 1200W...

TPA3251D2 - 2 x 175W stereo 350W Mono class-D amplifier

In analogy to the TAS family (TAS5630B, TAS5613A, TAS5611A), Texas instruments introduced a new class-d chip amplifier, the TPA3251D2 (HTSSOP44). Specs are: differential analog inputs 2Vrms 90% efficiency (4 ohm) 12-36V power supply 2 x 175W at 4 Ohms BTL (10% THD) 2 x 220W...

Layer structure PC9 0

ORWO Color Positiv-Film PC 9

PC 9 is a multilayer film consisting of three emulsion layers selectively sensitive to green, red and blue light. The two upper emulsion layers are stained with screen dyes to avoid diffusion halos. On the back of the film is a green antihalation layer...

Layer structure PC7 0

ORWO Color Positiv-Film PC 7

PC 7 is a multilayer film consisting of three emulsion layers selectively sensitive to blue, green and red light. A yellow filter dye is embedded in the top layer to shield blue rays from the middle and bottom layers. On...

Layer structure NC1 0

ORWO Color Negative Film NC 1

The ORWOCOLOR negative film NC 1 is a standard material that can be used for artificial and daylight photographs. In artificial light, one works without a filter and for photographs taken in daylight, the ORWO filter K 14 is used to adapt the material to the higher color temperature. The NC...
