This is a technical brief of ALTAIR05T-800, which is a 5W wide range CV-CC optoless adapter demonstration board, tailored for AC-DC chargers for mobile phones and adapters and other hand-held equipment.
The document details the EVLALTAIROST-5W demonstration board, which implements a 5 W (5 V/1 A) wide range mains battery charger. The core of the application is the ALTAIRO5T-800 IC, described as the first “All-primary sensing switching regulator” of the new ALTAIR family.
| Input mains range | 90 - 264 Vac, frequency 45 - 65 Hz |
|---|---|
| Output voltage | 5 V@1 A continuous operation |
| Regulation type | Optoless constant voltage - constant current output regulation |
| Standby mains consumption | < 100 mW @ 230 Vac |
| Average efficiency | > 70% |
| EMI compliance | EN55022-Class-B |
The board implements a 5 W (5 V/1 A) wide range mains battery charger.
No, the design eliminates the need for the optocoupler using primary-sensing feedback.
